Input: Saturday I'm out with a large group of friends for a birthday party. 

I come back in from the smoking area and start taking coat and sweater off. Im standing on the edge of the walking area between tables and the bar talking to a friend as I pull my arm out of my jacket a girl bumps into my elbow.

This starts a chain of events. She bumps into her friend and the drinks they are both holding spill upwards onto their chests, then they both drop the glasses at the same time, smashing on the floor spilling all over the place.
 
I turn around and the first thing I do is ask if they are okay. Then I apologize profusely, even though I don't believe this is totally my fault. If at all honestly.  I wasn't flailing my arms around, I wasn't purposely walking around slapping drinks out of hands. I didnt make a weird jerky move and I wasn't sloppy drunk either. It was an honest mistake. 

The girl smiled and said it was totally fine so i turned around and pretended like it never happened.

They didnt like that, and I was called a cheap asshole a few times by them passing by that night. 

I hate going "out" I cant count how many times someones bumped into me unintentionally resulting in me being soaked in alcohol in one of these places. 
Am I the asshole for not replacing the drinks? 

not buying drinks for girls that bumped into me and spilled at a crowded bar
