Ah, good to know, thank you. I understand why businesses are confused and don't even bother. I wouldn't either. I've had working dogs for 15 years and I still don't know what a service animal is, what a ESA is, who is allowed where and for why and/or how to indentify everybody.
I didn't know ESAs were allowed here, so as a business owner I would have asked someone to leave because I would have said ESA can't be brought in my store, only to find out they can and be sued. One county has one tag, the state has another, someone says the law says this, another says that. I'm as confused as the next person.
