Just remember the kind of people who work in those fast food chains. You will stop frequenting them.
We eat out quite a bit, at fast food places and others. Intellectually, I know it probably isn't such a great thing to do, but practically, I am so burned out on cooking that we just keep on doing it. We still eat at home most of the time, but when we're on the road working away from home, that 30 or 45 min. stop in the middle of a very long day on the road really helps to refresh. We have packed a little lunch in nice weather, but it is usually either too cold or too hot for stopping at picnic areas and sitting in the car is just too monotonous and not very refreshing.
