I used to keep my sailboat in a marina south of Annapolis. One weekend I invited a friend from north Jersey to come for a sail.
As we were loading the cooler for the trip we went to the ship's store where they had 2 large, self serve ice freezers and a drop box for the couple of bucks the bags sold for. He was shocked! He said in Jersey the money would be gone, along with the ice and there would be homeless people living in the ice lockers who would yell at you for disturbing them. Glad to know there is still somewhere that integrity matters.
It’s still common here in North Idaho. There’s a flower stand that’s also an honor system over in Rathdrum.
