You hand the cashier more money than the fuel will cost and go back in for your change. My rent-a-Camry takes about $45 for 3/4 tank so I give the attendant $60 to start.
The big gas station near my Omaha hotel has an entire wall of refrigerated beer and wines. Booze is cheap here. Try $7.99 for a six pack of Danish Carlsberg not the anaemic replica made in Oz by Foster's, $14.99 for a twelve pack of Heineken, $4.70 for a six pack of 16oz. cans of Old Milwaukee 5%. Bar in Cheyenne sold near schooner sized glasses of draught for $2.75.
