Giant Food / Giant of Maryland

Good Afternoon. I wanted to submit a complaint about the store in Washington DC, on 3rd and H street NE. This occurred 3 times but last was today around 2:30 pm, 4/7/2020. I have been coming to this store for over a year and sometimes with my puppy whom is always in a stroller. I had never been asked anything about her until recently on 3 occasions, two staff members and a police officer asked if she was a service dog. I stated no she is an emotional support animal whom I have paperwork on to take her everywhere I go. They all told there in disbelief and questioned me more as if I was lying. I pulled up my paperwork after being irritated and they said it was no need. Why question someone and when they show documentation yo support what they are saying - then proceed to say no need. They were all rude and Ive never experienced that at this store. I am a frequent shopper due to living right up the street. I can submit paperwork to corporate if necessary so that I do not get this same treatment again. Thank you.
