ELI5: How can Hooters hire strictly female servers without getting into some kind of legal trouble concerning discrimination?

I know this might be sort of an odd question, but if a male applied for a waiting position at Hooters (or a similar restaurant), what legally allows the restaurant to deny them the waiting position due to their gender?

There's a provision in the law which says
>Notwithstanding any other provision... it shall not be an unlawful employment practice for an employer to hire and employ employees... on the basis of his religion, sex, or national origin in those certain instances where religion, sex, or national origin is a bona fide occupational qualification reasonably necessary to the normal operation of that particular business or enterprise

(1964 Civil Rights Act, Title VII, Sec. 703(e)(1))

This means that you're free to use sex discrimination, if your business model *requires* people of a certain sex. The business model of Hooters is "boobs selling you chicken wings"; people without boobs can't do that.
