I was approached by an old white guy, maybe in his 70s, with a Trump Shirt, at Chili's on Veteran's Day yesterday. He asked if I was in the 24th unit, and I said "no the 25th". TRICK QUESTION. He said he was in Germany, and that they did not let Blacks serve over there. He left to the back, and came back and rubbed my dog Barack, who is a service dog. I was seated and eating my food. The waitress packed the rest of my food in a to go box because I had to go pick up my wife. I got my food and tipped the waitress. Then the Manager, MR. Wesley Patrick, comes from the same area in the back, walked up, and rudly informs me that a guest said that I was not a real soldier because I had my hat on indoors. Other guests heard him. He asked for my military ID, I was calm, and provided it to him. I also provided him with my DD214 which is my discharge paperwork. At that point he should have just said "I am sorry Sir, thank you for your service' Instead he followed up with "the guest also said your dog is not a service dog." Barack had his Red Service Vest on, and his Certified Service Tags. I was sitting for 35 minutes prior with Barack beforehand. At this point I was grossly offended embarrassed dehumanized and started Recording...Mr. Wesley snatched my food away, made body contact
