Complaint Review: United States Postal Service station M - Chicago Illinois

I had a very bad experience today at the United States Postal Service 7615 N. Paulina Avenue Chicago Illinois 60626. The postal representative for this location was obnoxious, angry, and irrational. She had no identification tag on her shirt and she refused to identify herself. Upon entering this location with my service dog the postal rep yelled at me as I was coming through the door "No dogs or pets allowed" In response I stated "This is a service dog Mam" she then stated "There are no dogs allowed. The only service dogs allowed are visual and impaired hearing. Look at the sign in the window". She never asked me what my disability was. Which was the first mistake. Secondly as I tried to reply again. "Do you have any idea in regards to the level of discrimination that you are about to embark upon"? She was in rage. However, I personally encountered the same rage from this very woman a few months back. Nonetheless, I asked the postal rep her name and she said "I'm the only one working here so everyone knows who I am". I then asked if I could record this conversation? She declined. I then asked if I could record the establishment? She declined. I asked for the final time "Are you denying me the right to deliver my package in a United States Government Facility? She stated again " Service dogs are not allowed unless a person is visual or hearing impaired. Once again she is not a physician and she never asked me my disability. I have never encountered a person who is a public servant with this level, and lack of knowledge in this area where the issue is  imperative and pertinent to the courts within a  system. I can not believe this woman had the audacity to bring the hood behavior into a government establishment. This woman was trying to argue with me like I was her boyfriend or husband or something. I stepped outside and  called 911 the Chicago Police. After about 30 minutes I called again. I knew it would probably be awhile once the dispatcher hear that it was a non emergency. The Chicago Police finally arrived. And this part you are not going to believe. By the way I stepped outside and walked maybe 100 feet from the building as I waited for the police. The police approached me and asked me "what's the problem"? We were standing in front of the building in front of the glass at the post office. When the lady walked to the door. Locked the door and put a sign in the window stating that she will be back at 4:10 p.m. The Chicago Police then knocked on the window but she kept walking. This is where knowing of the law comes in. If this woman felt as though she was right according to the law she could have directed that same energy to the Police. I don't think that she actually believed that I was going to call the police. Hood mentality. This is where the technical issue comes in play and this is the part that may cost you your job and also find you liable in a lawsuit. 1st officers name is Alonso badge #10003, 2nd officers name is Dayao badge # 16567. The beat is 2422 and the time was 1552 hours military time which is 3:52 p.m. The event # which is the body cam from the officers is 09259. This is how a person sills his or her own fate. Thank you for reading have a great day.
