You can hear a lot of funny things working behind a bar. If you aren't part of the original conversation, the things you do hear may seem random and not make any sense. I recently overheard a few things that were said where I was part of the conversation and they still sounded funny to me:
"Oh yeah. There's another $400 here!"
"Half the club smells like weed."
"No more shots for you!"
"How do I make a Hot Toddy?"
It seems like the later it gets, the more random and entertaining things people say. I chalk it up to public drunkenness. There's never a dull moment with bartending as long as there is alcohol involved.
