I find that most of the services I use for Thor - vets, daycare, grooming - want some "private time" with Thor, which I find understandable, because if I'm in the room, he's going to do anything he can to get back into my arms. I'm fortunate that I afford to take him to the most reputable places, not that guarantees good treatment. My rule of thumb is that he should be okay when he comes out and not mind going back.
His groomer is actually pretty snotty to me, but Thor loves her, so I trust that she treats him well.
