It doesn't seem to matter what the law says. As long as people think they're illegal, service dog nazi will remain an irritation to the disabled. It's pretty rare to see someone face heavy penalties for having a dog that has undergone public access training, for a legit medical reason. The biggest annoyance I've seen is being banned from stores. It seems to vary by community and thier respective tolerances. Usualy they just tell you and your dog to f*ck off, and if you show up later without the dog everyone moves on. There's also plenty of stores that respect you, your service dog, therapy lizard, or safety space hamster's right to spend all the money you please, in their fine establishment.
