At my work, they allow people to bring pets, however there was one lady recently who brought in her little dog wearing a "service dog" vest. It didn't matter as we allowed all dogs, but it's obviously not a service dog as the dog is just slightly older than being a puppy (and went a little crazy excited after it saw a baby looking at it) and she didn't appear to have any disabilities either.
But I mentioned I put my dog Zelda to sleep last year and she asked if I got a new dog. I told her I didn't get one especially as my house doesn't have a fence and my wife Daisy just isn't much of a pet person. Daisy hated taking my dog outside to do her business, and I doubt she'd be much help with a new dog.
She then told me to reevaluate my marriage to Daisy, because she didn't like animals very much. She also said I had to "be sure" before I ever had kids. You know, Daisy isn't perfect, but it sure is annoying to hear someone badmouth your wife when they themselves are liars and have no shame about it. All these people do is make it harder to believe the real service dogs and the people who need them.
