Ahh, these are the best customers around :)

I work at a bar with 80 beers on tap and 200 in bottles. People ask me to pick a beer all the time and I thoroughly enjoy it because I usually get to educate them on something they didn't know about beer. So yeah these are awesome customers.

I would have given em a medium water

This literally just happened to me a hour ago. I work at Buddy Guys Legends, and we sell T-shirts. People just always throw out a random size, and then just stare at me until I ask what exactly it is that they want.
