As per discussion at Is it legal to let people search for professionals by gender?, it was mentioned that customer satisfaction and preferences alone do not justify a Bona Fide Occupational Qualifications defence to a discrimination claim. Diaz v. Pan Am. World Airways, Inc. and Wilson v. Southwest Airlines Co..
It's also been mentioned that Hooters BFOQ defence has never went to trial, always going for settlement.
Doesn't it imply that anyone can just apply to be a waiter at Hooters, and upon being turned down for obvious reasons (of not being a Hooters Girl), seek a "free" settlement?
