It was a holiday weekend so my bar was DEAD. Like no barback or security guard even, just me.
This guy walked in with a couple friends and ordered the most expensive shots we have. His bill was $75 and he gave me a $100 bill. I returned his money in 5's and a $10 and he screamed at me that I clearly had never been a Bartender before because you never return money like that. He demanded singles while also bringing my attention to his Gucci wallet for some reason (further proving MY point that you can tip me $5 on a $75 tab).
I exchanged a five for singles and he left me $2 and walked away laughing. They then stayed for an hour ordered the same thing two more times and tipped nothing. And of course before he walked out, he called me a bitch. Because its my fault hes a cheap jerk right?
Separate occasion: I got slapped in the face by a customer because after I gave him his drinks. He demanded I show him my tits and obviously I told him to go fuck himself.
The kicker to this one? I had no security guard on duty and the owners exact words were, "Did you get the money for his drinks? You look fine, he must have not hit you that hard." and refused to kick him out.
I work at dive bars in Manhattan so I know what I'm signing up for but come on people! Human decency just doesn't exist.
