I don't know who's paying only 1.5% in CC fees, sure wish that's all I paid--

The reason for the CC surcharge is so cash payers don't get penalized for the CC fees-- the math is pretty simple: a 30 gallon fill at $2 per is $60, 2% vig is $1.20 Now simply do nothing but raise the price of gas to $5.50, a fill is now $165 and the 2% vig is now $3.30, a 275% fee increase that the gas station has to eat, and due to no fault of their own. Cash sales saves them money, so they offer buyers a choice..
