Input: There's this really attractive female bartender that works at the main bar next to my university. I (male) have been talking/flirting with her for the past few months every weekend that I go out. Typically, I'll be completely belligerent though and I usually struggle to remember our conversations the next day. Also, the bar gets packed and it's difficult to talk to her in the first place. 

I never really thought about making a move for a few reasons.
1. She's seen me hit on other girls consistently for the past few months.
2. She's older than me, working at a bar, and I assumed she didn't want anything to do with a guy still in college.
3. I didn't want to make things weird at the bar I frequent so often (shitting where you eat kinda thing)

However, recently she followed me on Instagram at like 4am without even knowing my username meaning she looked up my name (that she knew from my credit card). Also, the other bartenders told me and my friends that she was talking about me to them.

So I got hopeful and decided to message her on Instagram. She left me on seen then replied days later. I waited a few days and replied just to be left on seen again. I didn't really think anything of it, but then the next time I went to the bar, we barely talked and then she stopped serving me drinks because I was "too drunk" apparently. She went so far as to tell all the other bartenders not to serve me. I think this is because I didn't tip her since I was upset that she wasn't messaging me back. 

I was pissed off at this point and it probably showed. I was told later that I left the bar when it closed flipping off all the employees saying "I'm never coming back to this shitty bar ever again"

Then I unfollowed her on Instagram but she stayed following me.

Next weekend, I saw her and tried getting a drink from her. She walked right by and took everyone elses drink orders except mine. Finally she got to me so I asked if she was going to cut me off again. She said she would if I kept giving her attitude. I was taken aback and just bluntly told her to get me my drink. She slid me my drink and the check without even looking at me and walked away without saying another word. Again, I didn't tip her. 

I messaged her later that night asking why she was acting like that - just for her to leave me on seen again. I was blacked out drunk at this point so I got mad and decided to just block her completely. Today I unblocked her though and there was an unread message from later that night saying I was the one acting out, not her.

So AITA for not tipping her? Or is she the asshole for following me on Instagram just to not reply to my messages then give me the cold shoulder when she saw me? Judging by her actions, it seems like she was only talking/flirting with me before because I tipped her well. Then as soon as I tried talking to her outside of work / not tipping her, she felt no reason to be nice so she started being an asshole towards me. Curious to see what y'all think! 

not tipping a bartender I used to flirt with
