We got our credit card bill yesterday and found that a fairly new, neighborhood restaurant had double billed us for a recent dinner ($90 - not a trivial amount). My husband was furious and said that the only time he gets double billed is at small restaurants. This has happened before; the last time it happened, he called the restaurant, they said they would credit it and never did. He had to contest the charge. He thinks they do it intentionally figuring you will not check the bill that carefully, and in fact I had checked this bill and missed the second billing, so I would indeed have paid it.
I tended to think that new, small places may just be less good at things like this, but after this one I am beginning to wonder. Any other experiences with this?
