I was visiting in Pittsburgh on Saturday, and on the way back, I got burned by a gas station pulling the old "cash discount" scam. They advertise a low gas price - ten cents cheaper than the high end of average - and once you pull in & are halfway through your transaction, suddenly that's the "cash" price, and your credit-card/debit-card transaction was ten cents a gallon more - up over the high end of average again. They used to pull this crap a lot back when gas was relatively expensive - before the Reagan-era price collapses in the late Eighties. Or maybe it's just that I don't have to buy gas in Pittsburgh all that often any more, and it just seems like they've stopped with the "cash discount" bushwalla.

It was a place on Mt. Royal in Shaler Township, BTW. Just down the street from the local school.
