On road trips, sometimes there is no rest area nearby when a bathroom break is needed, especially with children. If you stop at a gas station/convenience store, do you feel obligated to purchase snacks or other things you don't want or need? I try to plan bathroom breaks for when we have to stop anyway for gas, but sometimes, it's just not possible. I always have plenty of food in the truck, but if I'm not buying gasoline, I end up feeling guilty if we use the bathroom without spending money. For a day trip, it's not a big deal, but for a cross-country trip, buying stuff you don't need each time your child has to go to the bathroom can really add up! So, do you make a purchase each time you stop or not?
