I have been harassed for bring my service dog to my office when it escalated into physical violence.  The man in the office next to me stared complaining as soon as I walked in as he does most every day stating I cannot bring my dog in here. I didnt have my dog with me at this time. When I told him  my dog was a service dog, he started screaming at me to leave. I refused because I work there and he was not my boss.  He then grabbed me, ripping my purse open and pushed me to the ground up against the wall. He got the office chair and attacked me with it , hitting me three times rolling it into me. Thats when I started screaming loudly. He stopped and walked away. I called 911.
