I was completely gobsmacked when my wife told me sure was used to eating fast food multiple times a day back in Utah. I made it quite clear that wouldn't be happening once she moved over here.
Here in Germany people usually don't go to fast food places to pick up breakfast, lunch and dinner every day. I'm not saying there are people who don't, but it is really unheard of. Fast food here is seen more as a "treat" (depending on your views) than a daily meal provider.
