wristbands

I stopped at a few Toledo clubs on my way back from Detroit yesterday and noticed their clubs put wristbands on you when you pay the cover charge. These were annoying and I took them off after I got inside. I think their logic behind this was to allow you to re-enter without having to pay the cover charge a second time. When I was leaving the door man stopped and asked if I wanted a wristband to be allowed to return later. I declined. Might also have to do with helping out the waitresses identify who is allowed to drink and who isn't allowed to drink because I saw two different colors (so I'm assuming one for 18-20 age group). I know several Columbus clubs don't even bother to let the 18-20 age group in because of the underage drinking problem. They used to make the underage group pay an inflated cover charge and give them a t-shirt to wear to identify they were underage but it was too easy for them to find ways to take off their t-shirts (I saw one in the bathroom stall before). I wonder if they do this every night or just on the busy Saturday nights.
