It’s their culture to complain about everything, except food. All they care about is that it’s as bland as possible and has big portions. If you manage that, they’ll give you five stars every time.
I spent 3 years living in Germany, and not only can you not get anything spicy for love nor money, they also don’t use herbs. It just blows my mind. They’re physically so close to France and Italy, but the food is so far away.
