Gas Stations

I have seen a disturbing return of a trend at gas stations that I don't like. After many years of having the price being the same cash or credit, the stations have now resorted to posting prices that are cash only, and until you are at the pump, you don't see that it is a cash price, with credit being 3-5 cents higher per gallon.

I understand that the credit cards take their cut, but at least make it obvious on the street sign what the prices are.
