Aisle officials
Somebody suggested grocery stores hire aisle officials. You stand in the middle of the aisle visiting with an old friend, you get a fine. Five dollars, and it goes up every time you do it.
I'm not saying I'd vote for it. I'm saying I'd want to see the ballot.
I can picture the official, too. Striped shirt, little whistle, standing by the canned tomatoes. Not mean about it. Just a polite tweet and a hand pointing toward the end cap.
I don't mind people visiting. It's one of the better things about living somewhere folks know each other. Catching up by the bread is practically a sacrament around here. Just do it over to the side, where the rest of us aren't trying to get to the milk.
Five dollars seems fair for a first offense. By the third one you've paid for somebody else's groceries, and honestly that might be the most neighborly part of the whole idea.
