I have a dog who was ESA certified. Dog did some work. But when I could not spend enough time to keep it up, I could not convince my doctor I had dementia. So he is not longer an ESA. Sad thing was, I saw people with fake credentials popping up all over the place. Hotels, air travel.
People are just fraudsters.
While mine was certified, I never took him on a flight, but he did travel to a few hotels on soccer road trips. I never took him to the fields, even though I could have. I never took him to restaurants, yet everyone else does. Nothing like fleas and dog hair for lunch.
I did once, take him in to Cookes in Malibu just to piss everyone off because I was tired of Paris Hilton and all the bitches bringing their bitches into the store. The store tried to tell me that Chihuahua is okay, 100 pound dog not okay. I said, here is his certification card, and by the way, your threat is a violation of the ADA.
But I proved my point, and never took him into a store again.
