Because you would be a representative of America, not a fucking dive, tattoo parlor shithole. Basically the same reason that I won't eat, or be waited on by, a fucking walking billboard usually with more metal on their face than on my Harley. They are a representative of the establishment who employs them, if they clearly don't give a fuck about their own bodies, then why the fuck would they care about what you're about to eat? What kind of message does that send to their customers? I don't want any clueless, white trash, all attitude, "body autonomy" SJW, lunatic, handling anything I'm about to eat.
