I work at one of the more prominent clubs here in the greater Oklahoma city area and believe me after a night of drunks, alchohol, and cigarette smoke you'd not only want to change clothes, but you'd want to scrape your skin off and leave it behind on the floor.
I go to Coyote Ugly (Washington DC) every saturday, and all the coyotes usually come in with something different and leave with something different. Its gets messy sometimes.
