Customer angry at 25c charge for dipping sauce

Manager of a Jason’s Deli actually wanted to charge me for an extra pat of butter. And that was after my bill had been rung up and paid for by credit card. Never went back. He lost a customer over 3¢ of butter. Filled out a customer response card and dropped it in the box, but never heard anything back, so he, or someone at the store, was removing any unflattering responses.
