Update: I am working with one of the owners to resolve this issue. She has been very understanding of my grievances and apologetic for the staff's treatment of situation. Additionally, the offending server no longer works at this bar so shouldn't be an issue in the future.Short version: I rented out the VIP section for my birthday party. The server refused to serve me after serving me only one drink all night. It was my birthday and I only got one very weak drink over 5 hours. We ended our party early because of it. DO NOT RECOMMEND AT ALL.Long version:I rented out the VIP section for my birthday. Around 12:45pm the issues began.First, the waitress initially lied to me when I asked for a glass of wine telling me "we're not allowed to switch alcohols." Maybe she thought I was asking for a bottle of wine but in all the years I've been going to Picks they have never carried bottles of wine. Instead they carry canned wine. Regardless, her telling me she couldn't switch alcohols made absolutely no sense given that many of my guests were drinking their own non-vodka based drinks.Second, I then switched my order to a single Tito's and Sprite. She went to the bar and came back telling me they could no longer serve me. She then turned to my friend right next to me and asked if she wanted another drink. My friend was working on her third straight double of the night. She was also not drunk (see breathalyzer comment below). For the waitress to offer to serve her and not me was insulting. The waitress wasn't cutting off anyone else in the party, only me. She singled me out with no proof of intoxication. When we asked her about it she just went back to the bar area.Third, we had to ask what was going on to get any sort of explanation. My friend had to go up to the bar to talk to the waitress and find out she thought I was drunk and cut me off.Fourth, when we asked to speak to the manager and he came over he never apologized for the incident. He thoroughly explained the bar's policy of allowing staff to cut off people they believe are drunk, which makes sense. However if we're all clearly sober and having a civil discussion about it then the waitress made the wrong call. Also, our waitress should be the only one that knows exactly how many drinks I ordered for myself. If she does not, then she's not good at her job. It was 1 coffee with Bailey's at 8:30pm and 1 Tito's and Sprite at 9:30pm.Fifth, the manager did not apologize for the incident or even offer to get me a drink on the house. Instead he said he would make sure I could order a drink. We had just spent hundreds of dollars that night between the VIP area and the bottles and his solution was I should be allowed to give the bar that insulted me more of my money? That's greedy and poor customer service.Lastly, I carry around a breathalyzer on my keychain because I won't drink and drive. I blew into that after being denied service and only blew a 0.015. The bar has camera footage showing me blowing into this. Later in the parking lot my friend and husband blew into it. My friend blew a 0.047. I don't remember what my husband blew but he was also below the legal limit. A large part of that is the shots we were taking were not straight alcohol but rather vodka and cucumber mixer so were not that strong.I ended up being the designated driver from my own birthday party that ended early.
