I meant "get caught" in the sense that one of the patrons grabs her and tries to grope her. Many times, the way the leash scenes are written, it clearly expresses an intent that patrons have to grab them or they actually do make an attempt, but the heroines and villainesses always seem to escape.
Though, now that you mention it, I think it would be enjoyable if the police were secretly investigating the Slam and you had horny undercover(and maybe uniformed) cops make lewd comments on how good the "performers" look.
