I can often get something to eat at the places I play. It's not uncommon for me to eat part of a meal during setup before the show, and put the rest in a to-go box and stash it in my car. After the gig I'm more occupied with tearing down and getting home. Fortunately, my house has an attached garage, so I can leave my gear in my car and I don't have to do anything with it until I feel like it.
Then I nuke my leftovers for a minute or so and enjoy the rest of my meal.
