Unwelcome sexual propositions are a very distant fourth on my list of worries behind blood-covered syringes, blocked toilets, and misplaced human waste, all of which I've had the misfortune to encounter as both a consumer and as a cleaner when I worked in a cheap restaurant.

By contrast, telling the occasional gay dude that his advances were unwelcome has been a very minor annoyance. I can see how it would be more offensive/unnerving to other people, but it strikes me as much less of an immediate health hazard.
