I don't like this gas pump credit card thing at all.

I quit using credit cards for gas, and motels/hotels. I'm doing "CASH" only.
I'm going back to the "old " rule of thumb for credit cards.
"If you won't have the item purchased, when the bill comes in, don't use the card."

However there are some things that work. I bought a late model car, on two cash back credit cards. One in my name, one in my wifes name. When the statement came in, I did a balance transfer to two other cards, that had a 3% transaction fee, and zero interest for 18 months. I have the cash available, but didn't want to deplete my cash available for emergencies. I will either pay off the balance in time, or do another balance transfer. (You must pay more then the required min payment)
I did the same thing, when I found a deal on some rental property, and didn't have cash available.
