One unintentional benefit of grocery store cashiers having to wear masks for months on end.

They are forced to find some way of opening plastic bags other than licking their fingers. I have to admit that, pre-pandemic, when a cashier was coughing and blowing their nose and then licked their fingers and then touched the groceries, I kind of felt it was only a matter of time before I would have a head cold. But now, it's more convenient to use a sponge or one of those "kwik sort" things or whatever they're called, since they have a mask over their faces. A lot of people are gonna break some bad habits.
