I have been coming here to Revolution Room for many years and enjoyed the diversity of the different sounds and atmospheres. Tonight was a different story. The bartender was extremely rude and when presented with the bill, they had added 20% gratuity/tip to the total. I asked the bartender if this was something new that revolution room was doing. She stated that they have been adding 20% for over a year and I must just not have noticed. She also stated that if you are one person or 20 people, they still add this. This I would have noticed before. I usually tip my barstaff well above 20% but to see this added automatically was downright insulting. I have never seen or heard of any place in San Antonio doing this. Granted in restaurants when you have parties of 5 or more this gratuity can be added but in a bar with two people? C'mon, this is ridiculous! Even South Beach only charges 18% gratuity and this is most certainly not South Beach! After sending so much business to Revolution Room, I'll stop. Avoid this place and take your business elsewhere.
