They have their card limits set to $75 so I can't fill my tank at current prices of ~$4/gallon. It's super annoying to leave the last few gallons of tank empty and I'm not going to do two transactions. I've complained to the attendant a few times and he just shrugs and says something crazy about people buying less gas not wanting to have over $75 of funding to enable the charge to be pre authorized. That's a crazy reason, as if $75 is some magical limit and $100 would be too much.
