Yes, once or twice I decided it wasn’t worth finding a signed credit card receipt from months ago, buried in storage somewhere, and decided to just ignore it. I’m sure the person was here…hell, even if someone stole their card and used it here, I’d be in the clear by presenting that to the processor, but sometimes it’s just not worth my time.
There’s a gas near me that uses a different name when they charge credit cards than what their sign says. It’s gotten to the point that when I see someone stomping in, credit card statement in hand, before they even start talking I’ll say “Does it say [my store name/city] or [gas station name/neighboring city]”. It’s funny how quickly they go ‘ooooh, that makes a lot more sense’.
