If someone truly wants an emotional support animal, they need to get a Golden Retriever, or at the worst, a Lab.
Aside from the fact that they are beautiful, Goldens are the most people loving dog by far.
A few years ago at Publix some guy was parading his pit bull with its service dog vest through the store. Saw him encourage shoppers and employees to pet it. I complained to the manager. He agreed it was not a service animal.
I told him I was very upset employees were petting this dog then touching food items I might purchase. Plus, thats not appropriate behavior around a true service animal.
Never saw it there again. I made it clear if that dog hurt me I would sue and testify on behalf of any other customer injured by that dog.
