I went to this gas station on my way to drop off my rental car. I filled up, and got hit with 2 charges, one for $81 and one for $31 (Texaco Airport). If I remember correctly, my gas was only $60, so I actually believe both of them were wrong, however I did not have my receipt and could not prove this.
While you're getting gas, they hold your credit card. I suppose its not impossible they accidentally scanned my card for another individuals gas, as there was one additional person at the station while I was there, however this would seem unlikely. Couple that with the fact that I really don't think my gas purchase was $81, and it kind of makes you wonder.
If you get gas here, you better make sure to check your receipt, and I would be interested to hear if there are any others that have had this happen to them.
BTW, this happened in October, just now getting around to posting about it.
