Can someone give me some support on this?

I went on a date with an older guy today, he seemed really nice online, when we met he was a jerk, constantly said racist things. So I suggested we walk around the mall instead of going back to his place, and as we were walking there he said he wanted to stop by this covid vaccine center. I was visibility confused and said it looked closed. He proceeded to ask me to come in. See i only wear a mask indoors because I have a breathing problem and live in a rural part of the city, but I'd never try to go into a building full of people trying to not catch covid to prepare for the vaccine. Absurd that he asked this of me! I am so angry and don't understand why he couldn't just say he had to get going. I ran down a dark alley and caught the train and honestly felt safer doing that then waiting for him. There were also a ton of cops and I don't think they thought anything bad of me. I honestly feel traumatized by this can someone please send me some positive vibes.
