My DW gets a receipt for every gas fillip and writes the odometer reading on it. She then puts the receipt in the glove box. She gets really mad if I fill her car and don’t do the same. This goes on for the time she keeps the car. When it come time to trade, I clean out the car and throw out all the trash in the glove box. Not once in all the years has she done anything with the information. This is the same women that complains about the price of gas yet she might drive 1-3 thousand miles a year.
