Do germans and austrians hate swiss people?

I am learning german in high school, and my german teacher is ethenically german but he grew up in america, he was describing the gernan speaking countries, and he talked about switzerland in a rude way, he was trying to imitate a swiss person and he said "Who needs to join your stupid european union, then we will have to give money to poor countries, were swiss, we,ve got mountains and lakes and we dont need to join your stupid union." Everybody in my class laughed, but I was actually offended by that. when I went to europe switzerland was my favourite country, and swiss people were the nicest Ive ever met, they were glad to help us if we needed directions and actually like the fact that you are visiting their country, while germans on the other hand were infact very rude and unwilling to help us if we were lost, and they looked at us as if I were a retard or something. so do germans and austrians generally hae swiss people, or is it just my teacher

I think that he is representing germans, because he said that he lived in germany for a few years, but hes actually kind of a funny teacher, he said that some perfectly normal words in english, mean something bad in german, such as light in german and mist in english, both mean something bad in the other language, mist means manure in german, so when he was playing basket ball with a friend and the other person's shot didnt make it, he said

you missed, which kind of sounds like
you mist, he had many other experiences like that
