I used to work as a barman go events at my local town hall. Working behind a bar, I saw a bunch of dumb things, but the one that stood out the most was on my first shift ever. A bunch of students who had booked a huge party at the venue went on such a huge bender that they tried throwing up in a jug for water. They threw up so much that it overflowed and covered literally every inch of the table. They were barred from the building and fined for the table cloth and jug, which had to be thrown away.

Very smart.
