Sex at the rest area, instead, abolishes identity theres a sort of freedom there to not be anything instead, men just meet other men there. At worst do not respond when someone else says hi or good morning to you. If they are gay and they ask you out simply say no, just like the ugly chick at the bar. At least have the decency to say hi to someone that speaks to you. men use signals like foot tapping when cruising for gay sex in public.
