1914 Lounge

Horrible service, i went to 1914 with two other friends, I bought 2 rounds (6 beers), they charged me 27 dollars when they were 3 dollars each, I asked the bartender if she could print out the detailed ticket (because the ticket I received just had the total), she told me she couldn t, I told her that I would like to speak with the manager, she said ok but never called the manager, at this time, another bar tender asked me if I needed something, I asked him if I could get a print out, he then gave me a detailed ticket. Bartender Erika charged me 9 beers instead of 6. Erika told me she couldn t do anything. Do they do this with all the customers?
