I find some pumps cut you off at $100. Then the next place you stop lets you put in any amount till you stop the pump. I try to fill up and it if cuts off before I'm done I don't let it bother me but just try to fill up at the next stop. What really angers me is the gas in all the states we travelled through on our last trip were cheaper than my own. I got back to Kentucky today and the first place I refueled was a total rip off. My home town city council is actually installing gasoline pumps to sell to the public at reduced prices because the local stations are all working together to gouge us.
