Unlike most people, I always pay CASH.
Sometimes when I travel, I go inside to prepay, I may have to wait for the guy buying $100 in lottery tickets. Then if I need change, I have to wait for the little old lady buying $50 in lottery tickets.
Lots of "skimmers" in pumps in Florida.
When traveling, I often see how many miles I traveled, what my indicated mpg shows, calculate how many gallons it will take, then multiply by the price per gallon. (I do this in my head). Then when I go inside to prepay, I round down to the nearest quarter.
Don't have to worry about skimmers getting my credit card information.
Works for me.
