I am a graduate student at University of Wisconsin-Madison (well over 21 years old), but I am originally from Maryland. Immediately upon entering the Nitty Gritty the bouncer told me "not tonight" and asked me to leave the bar. Considering that I am well over 21, it didn't even occur to me that the bouncer thought my ID was fake. So, I asked him why he was asking me to leave. He rolled his eyes at me and asked to see my Wisconsin student ID. I gave him my student ID and he proceeded to put my 100% real, state-issed drivers license in his pocket and asked me to leave. I guess he thought he was being clever, "If she gives me a Wisconsin student ID then she must be an undergraduate and cannot be as old as her ID indicates. It therefore must be fake!" I guess he conveniently forgot that UW is a huge university with numerous post-graduate programs. I basically had to pull a huge fit to get my drivers license back so I wouldn't have to go through the huge pain in the butt hassle of calling the police and having them get my ID back for me. This bouncer did not ask for any other forms of ID to verify that my license was real (I had to offer him my credit card and undergraduate student ID myself). He did not bend my ID or do any of the usual tricks to realize that it was not a fake. Instead he was just extremely rude to me and attempted to take away my very real and authentic ID. I am never going back to the Nitty Gritty. They need to hire new bouncers who are intelligent enough to know how to do their job and know the difference between a real ID and a fake ID.
