I also don’t think it is necessarily about respect or admiration. In day to day interactions, people just prefer to use the most efficient means available to understand and be understood. Like using English instead of a clumsy beginners level of Spanish.
Of course, but I can guarantee you that, at least for Dutch people, we have huge admiration for people trying to learn our language. Dutch is hard and the effort is appreciated, it shows a certain kind of respect towards the country and its people.
I can guarantee you that if someone at the counter gives the receipt and a foreigner replies with "Ja, graag" in a thick heavy accent she will be greeted with a smile.
I think that we switch over to English and the easy more default setting way too easily, this makes it hard for people to learn the native language because no one wants to practice with them.
