A neighbor and a niece, both work for banks. Both said that there is not a coin or bill shortage. They can order in, any amount of either. The problem is the stores, in that they don't want to handle the money, to keep the cashiers safe, and the buyer safe. Think back, was it this way prior to this covid-19. There in lies the answer.

I don't get this. Why would a store care if I paid for $100 of groceries with one hundred, two fifties or five twenties? I'm touching all the bills regardless of the denomination.
