Remember when a tank of gas cost $20? Between gas costing me $2.75/gallon now and a new 21 gallon gas tank, a fillup for me is over $55. Je suis Californien.
But the two gas stations I go to in the Bay Area have $48 limits on credit card charges. They won't let me buy a full tank of gas. I asked the guy at Valero about this, he said the limit was set back when gas was $1.30 a gallon. Clever.
