Shell

This gas station has a sign showing two different prices, one for cash payment and one for credit payment. I went inside and paid $20, yet they still charged me the credit price, which was a $0.20 difference. Unfortunately, though, I didn't notice what I was paying per gallon until I drove away. It may not seem like a huge thing, but it is to me and shows shady business practices. Not sure I'd stop here for gas again, but if I did, I would make sure they charged me the correct price.
