Recently I bought some Belgian Endive at the grocery store. The clerk, clearly unaware of what the vegetable was, charged me for Baby Bok Choy instead. The Bok Choy was more expensive by a bit, but I figured the difference was not worth mentioning... 10 cents or so. I remained mum.
On Saturday, we were overcharged $2.37 for something else. I thought of the avocados I've been avoiding because they're too expensive. $2.37 could buy me enough avocados for a decent sized bowl of guacamole. So we spoke up. The clerk insisted he was in the right. We calmly, kindly, but persistently maintained we were overcharged. A manager was called, the error was discovered, the clerk blamed it on the computer, the refund was given (there was no one behind us in line, by the way).
Was it worth the little scene for $2.37?
There have been dozens of small examples like this which, cumulatively, add up to quite a bit. I dislike confrontation, but I don't like squandering our hard-earned money on incompetence, either.
Who am I to decide that 21 cents is insignificant, but $2.37 is worth mentioning?
Do you speak up when you're overcharged? If the clerk insists he's right, do you "let it go" or do you pursue the issue? At what point is it "not worth mentioning"?
