Bubbly Booze Bar Brawl
When I was a bartender, this guy showed up (30 something, suits, looked like an jerk) and asked that I sold him and his friends (5 people) all the champagne I had, I said no, I would sell him 2 bottle and he could order more after.
I sold him the bottles, went for my smoke break and 10 minutes latter I saw him and his friend go out in the street carrying as much bottle as they could and start smashing them on the road, screaming and laughting.
Turn out my coworker agreed to sold them the entire stock and bring the case to their table (in exchange for a nice tip). So here they where, smashing bottle of champagne running in and out of the bar to get more.
We manage to stop them and call the cops but they took their car an ran off before the cop showed up.
The bill: 3 of them paid 2 000 € with their credit card and one gave around 5 000 cash. Story Credit : Reddit / BatouMediocre
