I've known of studios that actually won't let students take classes if they've been exotic dancers.  This is discrimination.  Can businesses actually refuse clients like this? I don't think they can and I've often wondered how this studio gets away with this operation.  I would never deny someone coming to my classes for any reason unless they are under the influence of drugs or alcohol and posing a danger to themselves or others.  Luckily I haven't had to experience asking a student not to attend a class for this reason.  I think for competitions, the fact one has been an exotic dancer is irrelevant.
