<prompt> Human: I noticed a restaurant over-charged me over the past weekend by a few dollars. Not a lot of money, but enough that I am annoyed. I dont really want to walk back in there just to confront them, especially over a small amount. Instead, Im thinking of disputing the charge through American Express.Is there any downside? Will it hurt my credit score, or some other consequence that Im not thinking of? Thanks everyone.  <response>: Ive only disputed one charge, and one of the first questions asked was what steps did I take to resolve the dispute with the company?You need to go in, or at least call and talk to the manager of the restaurant. It is not uncommon for a server to pad their tips by increasing the credit card charge a couple of dollars, and the manager is going to want to know if that is happening.
