If I find more of them with this crap, I'll make note of them and just swing in to buy $1 worth of gasoline then go to the nearest station where I can fill it up. Credit card companies normally charge a "per transaction" fee on top of the percentage.
Or I can just play a game to see how small of a charge I can make on the pump. I doubt I could hit 1 cent because I can NEVER get it to round up to an even dollar amount without going over. I'll bet they never thought to try to implement a MINIMUM amount.........
The oil companies raised the prices forcing us to have to spend more than $50 per fillup. It wasn't my idea, so don't penalize ME for it by making it damned inconvenient to fill up my gas tank when I need to do so.
