Hi, Franc!

Yup!
And the best the poor clerk could offer would be not to use your credit card. Or debit card.....same difference.
We have one processor for all credit cards we allow & they dictate this insane policy. And, they all set these limits so it doesn't matter if you go with company "A" or company "B".
I don't want to come off sounding like our company has these high standards unbeatable by the "limit retailers". We could very well do the same thing starting tomorrow depending on just how much we start losing. We don't make much in gas sales, the money is in inside sales. We make only a few cents per gallon (honesty, I've seen the spreadsheets!!); more when the price starts dropping. With the credit card fees on top of trying to keep up with the station down the street our gas margins suck.
So, please come inside & buy a Snickers bar!
Or better yet, a six-pack!!
