I just hate it when I'm trying to get out of the way of the crowd and forget to reset the trip odometer. It isn't a huge deal since I can just subtract the next time I fill but it's annoying. The older I get the easier it becomes. I'm fortunate though that the annoyances in life are so small.
Sorry, I lost this thread somehow. That would be an option but I just try to input the info while I'm filling and then only the gallons is left afterward.
