I always did it. My wife had an envelope to hold the receipts. We bought virtually all our gas at West Alton, and they always gave us a receipt with our name and bow number on it. When we pulled the boat at the end of the year, I topped off at the Alton Circle gas station.
Never had a problem with the credit card receipt from there, with my name from the card and boat bow number written on it. Loved the springtime mad money to buy steak or a bottle of booze, or.....
Alas, in 2019, not enough gas purchased to reach the $10 minimum.
Boat sold this past December. No more high mathematics.
