How to Decide Who Buys the Coffee in Under a Minute

From the moment someone says "Coffee, anyone?" after a team dinner until it's finally settled who pays, there's a running joke that the average office worker burns three to seven minutes. And those three minutes are really just "the person who always pays" sighing and getting up. Today, let's cut it down to one minute — seriously, it can be done ☕.

1Why exactly "one minute"?

Once you go past three minutes, the mood starts to feel a little off. Whoever pulls out their wallet first ends up paying, and when that keeps happening, an unspoken "coffee hierarchy" takes hold in the team. The only real fix is to settle it randomly within ten seconds. The idea is to leave no time to overthink it at all.

Here's how the minute breaks down: ① pick a method in 10 sec → ② enter names in 30 sec → ③ spin and get the result in 20 sec. Total: 60 seconds. Time it yourself — it really fits in that window.

2Use a different game for each situation

What you use depends on the headcount and the vibe of the table. Just pick by this chart and you can't go wrong 👇

💡 The chart below is a recommendation for "which game is fastest and most fun for this many people" — it doesn't mean "this game only works up to this many people." Each game's actual maximum headcount is laid out at the end of the article.

3The one-minute flow with roulette

0:00 - 0:10 · Declare it

One line: "Hey, let's spin the roulette." You need this declaration so nobody can say "Wait, I didn't agree to that" later. Get a quick agreement that the decision is being left to chance, however brief, before you start.

0:10 - 0:40 · Enter names

Tap them in one by one. The Lucky Please roulette auto-saves your most recent participants, so from the second time on it's a single tap on a preset chip. If your group is the same every time, 30 seconds drops to 5 🏃.

0:40 - 1:00 · Spin and share

Tap Start → 10-second animation → result. Hit the KakaoTalk share button right next to it and fire it into the group chat, and the "Mr./Ms. Coffee" meme season is officially open. You'll have something to tease them about at the next team dinner.

4What if someone wins twice in a row?

"Ugh, me again..." Two in a row, and people start to doubt the randomness. Statistically it's not strange at all, but the sense of fairness takes a hit. Three tricks to prevent it:

• Drop the most recent winner: just leave them out when entering names. Simple, but it definitely works
• Rank with the ladder: first place exempt, second place buys only drinks, third place even buys dessert — spread the load so it doesn't all land on one person
• Split into two teams and the whole losing team pays: team luck instead of personal luck. The "why is it always just me" feeling drops sharply

5Leave it as a meme in the group chat

A bet stays fun only when the result gets recorded. If it lives only in your head, nobody remembers by next week. Three little devices:

• Result screen → one tap on the Kakao button → straight to the team group chat
• Slap a caption like "2026-04-19 Cheolsu Kim won ☕" on top of the screenshot
• At the end of the month, tally up a "Coffee Person of the Month ranking" → surprisingly fun

The Kakao button on the Lucky Please result screen pops up the friend picker right away, so you don't need to copy-paste anything.

6Frequently asked questions

Q. Does it really fit in one minute?

Yes, really. With 5 people, 30–45 seconds is plenty. Entering names takes the longest, but with saved presets that drops to 5 seconds.

Q. What about a remote meeting?

Share the roulette screen, hit Start, and everyone watches together. When it's done, drop the URL in the chat and the proof is complete — the winner's info is baked into the URL, so there's no suspicion of tampering.

Q. Can't we just play rock-paper-scissors?

Sure, you can. But the result vanishes. With no record, you can't prove gripes like "I'm up for the third time this week." The key strength of digital randomness is that the result sticks around.
