Having been screwed multiple times by credit card companies in the three
years we've been a vendor (at the hotel), I can tell you that credit card
companies are run by the biggest pack of scum on the planet. They will
screw anyone and everyone, without provocation or excuse, to make a
nickel.

Now you're coming off as the whiney one. Birds of a feather with the OP?

Well, we may both be whining, but we're certainly seeing the issue from
different ends of the telescope.

He's worried about getting screwed by a fellow pilot who used his unused
credit at the pump. Others have suggested that he inform the credit card
company, in an effort to receive credit for the "unauthorized" charge.

I, on the other hand, am speaking from experience with dishonest card
holders who dispute legitimate charges, and are backed up by their
criminally complicit credit card companies. If the original poster informs
his CC company, and they actually credit him back the disputed amount, they
WILL charge the FBO, no questions asked, sight unseen. It is their standard
policy -- and the FBO will have very little recourse.

Bottom line: CC companies NEVER lose.
