I was practically refused entry into a store by some maniac who knows my name and who refused to come out

I pulled into the parking lot of a store to get some household items I needed and noticed the guy from the gym who coerced me to give him my name. He was walking in, so I waited to see him come out before I was about to go in. After 15 minutes though, he didn't reappear, so I just left. I didn't want him calling me out by my name in the store especially when I barely know him and I have nothing to say to him.

Now, I have to wait to get the household items... hopefully tomorrow.
