45 Minutes Between Two Golf Rounds: The Cocktail Accounts for Only a Third

In November 2026, at a golf course north of Binh Duong, I sat beside the 18th hole with a notebook and a tablet. My day job is data consulting for a football team, but the pandemic taught me one thing: operational data behaves the same way everywhere. People argue with feelings; the evidence stays behind in the record sheet.

That afternoon two groups teed off eight minutes apart. Group A, four players, finished in 4 hours 47 minutes. Group B, also four, finished in 4 hours 02 minutes. A 45-minute gap, same 18 holes, same wind, same course.

In my log, Group A ordered drinks six times. Group B ordered once. Three weeks later a reader emailed me a three-page Word document arguing that made-to-order cocktails from the beverage cart were the culprit, along with iPad payment screens and tip prompts. His proposal: if you want to keep time par, stop selling anything that has to be poured.

A tidy argument. Far too tidy.

Pace of play is an old subject in world golf, but in Vietnam it has only become hot over the past five years, as course numbers grew fast and weekend tee slots turned into a scarce resource. Industry estimates put roughly 80 courses in operation nationwide, most of them living on green fees plus ancillary services, and every tee slot that gets clogged is lost revenue. That revenue structure pushes the pace debate toward player behaviour — drinks, phones, music — because those are the visible things, and the easy things to ban.

The Pace of Play Manual published by the R&A and the USGA in 2026 recommends tee intervals of 8 to 11 minutes, depending on course difficulty and the standard of the group. That is the only pace-related measure in the whole document you can put a stopwatch to. Everything else — searching for balls, club selection, conversation, buying drinks — is a consequence of it. On the PGA Tour, officials monitor groups at checkpoints and publish an expected time for each round; at club level the equivalent tool is called time par, and mostly it exists on paper.

At the course I was tracking, the weekend tee interval was seven minutes. That is the starting point for every calculation that follows.

I broke the 45-minute gap into four parts.

Six drink orders accounted for 16 minutes. I timed each transaction from the cart stopping to the cart rolling, an average of 2 minutes 40 seconds. My reader saw this line, and he was half right: poured drinks genuinely eat time, especially when three different orders have to be mixed for three people on the same cart, then a card gets swiped, then a tip tier gets tapped.

Next came ball searches and club discussions. Group A lost an extra 9 minutes across the round. I counted 14 occasions where one player asked someone else to read the lie before hitting. Group A had a beginner in it, and there is nothing blameworthy about that.

Walking speed between holes added roughly 6 minutes, because Group A moved more slowly on foot.

Those three items total 31 minutes. Fourteen minutes remain, and those 14 minutes do not belong to Group A. They are the time the group spent waiting on the 12th, 15th and 17th tees — waiting on the group ahead, which was waiting on the group ahead of that. Fourteen of the 45 minutes of difference were not created by player behaviour at all, but by the course's tee-sheet design. That is the part almost every pace-of-play argument I have ever read leaves out.

The mechanism is arithmetic, not psychology. A course has 18 groups rolling around it. A seven-minute tee interval means the next group has only seven minutes of buffer before it touches the one in front. When a group takes 2 minutes 40 seconds for a drink order, that buffer disappears and the full delay transfers intact to the group behind. With a ten-minute interval, the same behaviour gets absorbed across most holes. One cocktail, two outcomes, depending on the tee sheet.

Delay on a golf course behaves like traffic on a motorway: one car braking in the inside lane creates a wave of congestion behind it, and that wave grows over time rather than dissolving. A group stopping five minutes on the 5th hole can become fifteen minutes of waiting on the 13th, if group density is high enough. A marshal cannot fix that by talking to people. Only buffer can fix it.

At most Vietnamese courses, time par is not published to guests. Marshals issue reminders by feel, and the standard shifts with whoever is on shift. That is why some players react badly to being nudged: they have no yardstick to check themselves against. Posting time par on the 1st tee board is the cheapest thing a course can do, and in my tracking experience it is also the thing most often postponed.

I re-checked against 42 rounds logged in the last three months of 2026, when the course was quiet. The correlation between drink orders and total round time was positive but weak, around 0.3. The correlation between number of waits on a tee and total round time was much stronger. A sample of 42 rounds is small, I could not control for the standard of each group, and weather varied between logging days. I would only call this a signal, and the signal is clear enough to revisit the original assumption.

Data does not lie. But reputation whispers into the ear of anyone who will not read the table.

The cocktail has a bad reputation. It is visible, it is loud, it is attached to the image of the over-relaxed golfer. The tee interval is invisible: a parameter in the booking software, decided by the commercial department every Saturday morning, and it never comes up in the conversation at the 19th hole.

This is where I remember what I wrote about Germany in 2026. I said before the tournament that the machine would rust. Not because I am clever, only because I did not believe the myth. Here it is the same: people need a culprit with a shape, and the cocktail fits the bill. The tee interval — the thing that damages pace more, and the thing a course could fix with one line of code — stays out of sight, because fixing it means fewer paying guests per day.

I hate uncertainty. But 2026 taught me that one unforecast variable can be stronger than any algorithm. In this story, that variable is the course's own cash flow.

On-course drinks are a profit centre, and the margin on a poured cocktail is far higher than the value of each extra minute a tee slot is occupied. If a course has to choose between cutting two tee slots a day and letting a group sit ten extra minutes on the beverage cart, the practical choice has in most cases already been made. That turns every call to ban poured drinks into a treatment of the symptom.

One detail in my reader's document was accidentally spot on: the iPad screen and the tip prompt. Payment latency is a modern, real, measurable variable, and the easiest item on the whole list to fix — batch the order before the cart leaves the station, or let players pre-order through the course app.

I do not predict. I read the data and accept the consequences.

If you run a golf course in Vietnam and want better pace next high season, the first thing worth changing is not on the beverage cart. It is on the tee sheet for peak hours. One concrete recommendation: set a minimum nine-minute tee interval between 6am and 9am at weekends, and compensate by pushing the last tee time of the day 20 minutes later so total capacity holds. It is a trade that can be verified four weeks later using the same notebook I am using.

Whichever course tries it first, I will be tracking. Whichever course bans cocktails first, I will be tracking that too, and I will guess the outcome in advance: pace barely moves, drink revenue falls. I can be wrong, and if I am, I will write it up again with the numbers attached.

Players do not have to wait for the course to do anything. There is a free change any fourball can make this Sunday: order drinks once, for the whole group, at the 9th hole. Six scattered transactions become one, saving around ten minutes, and nobody gives anything up.

In Group A that day, one woman ordered a salted lime juice on the 14th. It cost her three minutes, and in those three minutes the group behind had already piled onto the tee. She was also the one who spoke last as the group left the 18th in the fading light: that was really fun today. Pace of play belongs to scheduling, not to morality, and scheduling always has a fix.
