Having three kids and having a pretty active lifestyle means we often get food on the run. I am not great with being frugal at the drive through. I don't think about the overall cost but rather just get what everyone wants. My bills for family excursions are close to or over $20.
J-Mom is wonderfully frugal when hitting the drive through. She just seems to inherently know what to get to feed the crew on a budget. I guess I get anxious at the order screen, worrying about people behind me.
We need to cut down on it, though, and are trying.
