I don't generally "go out" for fast food. Actual sit-down restaurants, yes. Fast food, no.
I do enjoy fast food, but I indulge more out of necessity. When I'm already out or if I'm in a hurry. Something you pick up at lunch or dinner when you're between destinations or need to save time at home (go pick it up for the family, for example, while they take care of whatever).
So, I take fast food home
