Against government law they asked me if my small dog was a service dog , then because She was an emotional support dog, she showed me a picture of what a service dog has to look like( a German shepherd) ,, and told me I couldn't come in. Even though I had the necessary paperwork from a physician.She wouldn't even look at it. What she did I have been told is against the law. They have to stop this. We won't be back.
