There was a sandwich shop I used to go to where they had a bell and a tip jar at the cash register. If you put money in the tip jar, the cashier would ring the bell, and all the employees would shout “grazie!” After the first couple of times, before leaving a tip in the jar, I would ask the cashier not to ring that bell. I just imagined having to shout out a response myself every time I heard a bell. Very Pavlovian.
