Went to the gas station yesterday to fill up the pick up, (26 gallon tank) and two 5 gallon gas cans for the lawn mowers. I normally pay cash at a station close to where I work, but this time I stopped at a station close to home. I knew it would be quite expensive so I prepaid with a credit card. To my surprise they would only let me pump $75 of gasoline. At $4.30 a gallon that is less than 17.5 gallons. What's up with that?
