We had a SS-service-animalus on our recent trip. DP has a legitimate service animal, well trained (how many dogs will sit still on a lap while their human is getting communion? Or sit at a table while their human is eating lunch and never move? Our dog. Good boy!) and he wears a vest with a photo ID (from our vet's office) that has his shot records, identifying info, etc. We haven't had any problems traveling with him, and he is welcome (and a little fawned over) most everywhere we take him. Enter the SS people. They had a 'service animal' with them on this church conference trip. No vest. Wouldn't sit still. Lifted a leg on a chair DURING WORSHIP. Barked at the ushers, and forget communion - his owner had to remove him. Then they had the audacity to complain to the hotel staff that our dog was allowed to stay and they were asked to leave with him on day 2 - after he'd kept half a floor up all night barking every time someone moved outside the room (they were near the elevators, with traffic past the door all night). They apparently decamped to a more 'animal friendly' hotel nearby, but kept shooting us dirty looks all week.
The kicker? At the first day's 'accessibility needs' seminar, where we were encouraged to ask questions related to accessibility needs, the owner of said 'service animal' stated that the dog was a 'companion animal'; in other words - a pet. No owner disability as far as they stated - didn't ask for interpreters, no visible disability, didn't ask to be seated in the special needs section, didn't ask for a key to the 'decompression' room they set up for people with panic disorders, nothing. I think they just didn't want to board their pet.
I was very proud of our non-SS service dog, though. Not every service dog can get calm about people coming up to him and petting him without warning - but apparently, a six pound poodle in a shirt, even if he's wearing a service vest and sitting in the lap of someone in a wheelchair, is fair game for all sorts of attention. He was just as you'd hope - calm, accepting of whatever happened, no growling or biting, and totally ignored everyone when he could.
