Ban drinks on the floor, and only serve them in sex-segregated areas. Have bouncers to enforce this. (Bouncers and bartenders could still be male, but in uniform.) A rapist would have to have a female accomplice, successfully pose as a female (difficult for most men), steal a uniform, or actually be a female (this has got to be rare), and then still somehow get their mark out of the female area against her will without the bouncers noticing. This wouldn’t stop the boys from getting raped, but I assume this is less of a problem?
