On a related note, one thing I'd never thought about until actually being served by a masked waiter last month was that, pandemic aside, I kind of liked it as a general protection against having them accidentally breathe or spit on my food.
I could see the mask policy remaining popular for chefs and/or waiters indefinitely, just as a logical next step after hairnets and gloves.
So what? The staff wearing masks are somehow Untermenschen? You get to be a dick to them with impunity? You see them wearing a mask and just can’t help it?
