Yeah, I've found it really depends. Shortly after I came here, I had one Swiss person say in a huff (and in perfect English!), "You've been here for three months, and you still don't speak French?" How long ago did you live in St. Gallen? These days it seems like there's a bit of anti-foreigner mentality, so I've noticed I get a warmer reception if I at least try to speak the language.
