Peter Piper Pizza review: Discrimination

I went to the peter piper pizza on University Dr in Edinburg, TX and they were extremely rude to me and my service dog. First they told me that my dog had to have a vest and they refused to attend me because of my service dog not having a vest, I am not sure how educated they are but my dog does not need to have anything on his that says service dog as long as I tell the employee they should respect it. I don’t know if they know that by law I can sue the place. Also the manager told me that she was going to call her gm and her gm told her that no I could not stay inside with my dog because he was no on a leash. My dog is a diabetic alert dog and he needs to be around my chest level so he could be able to smell my breath. This was such a terrible experience! I can’t even believe it!
