I came in earlier today with my friend and her service dog in training (my service dog was at home), we walked in, got our food, and sat down to eat. We were not seated for 5 minutes before the employee who served us came out and asked for papers, we politely explained that there are no papers in the USA and that registries were scams, she then went in the back and got the owner, when the owner came out she immediately screamed "who's gonna sue me?" And then proceeded to ask if the person with the dog had left. She. Didn't. Know. He. Was. There. He was under the table sleeping. We raised our hands and she proceeded to come over to us already obviously irritated, asked us for papers to which we politely declined and explained again. She repeated herself again, and I gave her the ADA.gov website along with tge specific section that adresses service dogs. She proceeded to insult her dog repeatedly and threatedned us with the police and health department who we told her to call. She went in the back to call them and did not come back out. I have severe anxiety, PTSD, and panic attack disorder and was visibly shaking and bordering on a panic attack, while my friends dog was alerting her to high blood pressure. Over all this has been the worst customer service, Ada compliance, and arrogance I've experienced in my 3 years as a service dog handler. Me and my family have been loyal customers since they opened, but will never engage with them again.
