I'm not sure if this topic has been addressed before, but here goes. Gas Stations who charge differently for cash and credit. The worst offenders are the ones who prominently display the cash price and hide the credit price. Normally, I boycott the stations which do this. However, when you make your way off the expressway and follow the exit to the gas station while you're pulling a big trailer, and finally maneuver into the gas station only to find out that you've been duped... It's hard to pull out and find another station. Especially when the majority of stations are doing it and the next one might be the same. Any one else feel this way?
