Have you ever driven off with the gas hose still in your car?, They charged my credit card $300.00! Options

I was in a big hurry, trying to get gas and fill my windshield washer reservoir and running late for a Christmas gathering because my wife takes 2 hours to get ready, and I drove across the parking lot with the hose still in my gas hole. F&^K!
I ran inside and told the guy what I'd done, left my phone number, and left.
They charged my card $300.00 without even telling me, no call, nothing.
It looked like a quick disconnect was just pulled apart, it looked like you could just plug it back together. $300.00 for that?

Well, I talked to the manager today, and he was not a dick. He said he was sorry about the charge, that it shouldn't have been charged, and he credited me back my $300.00. He was able to produce a legitimate receipt for $220.00 for repairs, $120.00 for parts, almost $100.00 for the service call and labor, and some sales tax. He told me that I don't need to pay him right away, that he won't even be billed for 30 days, and that I didn't even need to come up with any money for 5-6 weeks if I don't want to. I told him that I'd come in in the next couple of days and pay.
The manager does look like the picture, without the beard. The family is Syrian. They're not Moslems but rather Christians, so the beard and Turban aren't necessary. I'm not looking to start up a religious debate, just making a shallow observation.
