I was standing in line at the grocery store, waiting my turn. I had my stuff on the conveyor. The woman in front of me was paying for her stuff and having a bit of trouble with her debit card and the card reader. The young man had her pull her card out and restart the transaction.
I felt sorry for her. She was embarrassed, but the young man waited with not one sound of impatience, which I thought was very kind. I looked over at him to say something...
...he was standing at his register with a far away look on his face
HE WAS PICKING HIS NOSE!!!!!!!!!!!!!!!!!!
The transaction completed at about the same time, and he handed the woman her receipt and began picking up my items one at a time to scan them.
I stood there stupified and silent. I wanted to say something.
What the hell is wrong with you? GROSS! Get your hands off my food. I decided I don't want to get groceries today. Yo, buddy, you ever hear of covid?
Most of my best responses come well after the fact, and as usual, it occurred to me as I put the groceries in my car, that I should have simply said, 'Hey...do you mind using some of that hand sanitizer before you start ringing me up?'
I imagine that is how Ms Manners would have handled this.
