I dined at a restaurant a week ago, and the bill came to $250 before tax.
I intended to tip $60 but accidentally punched in $600. I realized this after a week when I was sorting out my credit card receipts.
Question 1. Is it OK to ask for a partial refund ($540) on the tip I gave?
Question 2. If the restaurant refuses to refund, I suppose there is no way to fight it?
