Beware of this club. On...

Beware of this club. On May 22, 2005 within one hour of closing time, I entered this club and ordered a beer from a waitress and gave her a $20 bill. She returned with $6 in change. When I called her on the discrepancy, she said that I only gave her a $10 bill. Seeing that I was in a no-win situation, I left the building. While relating the story outside in the parking lot to another patron, the waitress in question came out to the parking lot and began berating me saying that I had "a bad attitude". Trying to keep my cool, I explained my side of the story and told her that I had planned on dropping a considerable amount of cash at this establishment and that I didn't deserve to be ripped off. This resulted in the waitress hurling more insults at me. At that point, I just left. I have previously had good treatment at this establishment on other (although infrequent) occasions. Hopefully, this is a case of just one bad employee or just a bad night. Maybe I'll give it another chance... or not. Does the ownership even care how the patrons are treated?
