I just moved to the neighborhood and I was extreme...

I just moved to the neighborhood and I was extremely excited to try this place, just a block away from my home. I brought 3 friends with me and lucky us it was 2 for 1 happy hour. Two of my friends went in before us and asked for water, because they were not drinking. The waitress threw attitude immediately and was clearly mad they weren't ordering drinks, even though they ensured her that we were coming in and about to order. I ordered one gin fizz and was going to give the other one to my friend who was drinking. We CLEARLY only asked for two drinks (the buy one get one). When the waitress came back she dropped off 4 drinks, we immediately told the waitress this was a mistake and we had only ordered 2 drinks and that she was charging us incorrectly. She fought us and stated that their policy was that they wouldn't split happy hour drinks, even though I paid and stated that when she was at our table. She was extremely aggressive and refused to admit her fault, fighting us to the end. Saying, "We do not split happy hour drinks, I didn't make a mistake. Do we have a problem here, I will just go and get my manager". We didn't even touch our drinks, I was very upset and suggested we just leave after I had already paid and left a standard tip. The manager comes over to us and insists the payment is accurate and said repeatedly that he would speak to the incredibly rude waitress. It would be one thing if they had disclosed that they do not split happy hour drinks and we would be getting four drinks, but it was never said and we were absolutely charged incorrectly. We dealt with MULTIPLE rude and passive aggressive comments from our waitress. It was clear she made a mistake and refused to change the bill. I didn't mind paying for it and absolutely didn't refuse to to tip on a bill I was incorrectly charged for. What I could not handle was how rude our waitress was and how poorly it was handled. From a customer service perspective I have NEVER been treated so poorly in my life and it was clear she felt she could take advantage of us because we were young. I have been dying to check this place out and the vibe when we got in was amazing, heck they were doing piano covers of the beastie boys. However, after being treated so poorly I will never come back. I have never been rude or demanding to a service person but I believe this server should be let go and I would like to be contacted by a manager or an owner to be refunded as we didn't even touch our drinks and it was so clearly not what we expected or asked for. I have never walked out of a place or left a full drink on the table but I walked out of there so mad I couldn't even think.
