Feel like I messed up with a guy, should I try again or just quit it?

Firstly, please don’t hate on me for this, I’m only just back to dating after a LTR and relearning how to flirt with new people!

I was in my local store packing my shopping when I looked up to see one of the employees standing nearby, staring at me. I thought he was trying to get my attention, but he didn’t smile so I looked away and left, but noticed he was watching me as I drove away. The next time I went there, he was stood out front and I saw him looking at me as I walked up to the store, he looked a bit nervous. When I was in the check out line, I noticed him peeking at me from outside and when I was packing my shopping he was now stood inside in the same place, watching me again. Maybe I should have gone over to him, he’s really attractive, but I got a bit nervous and left when another customer was talking to him. After that I felt bad about avoiding him and on the next couple of visits I tried to make eye contact to show interest, but I was so nervous I forgot to smile and now he seems nervous around me. He stares at me, but looks away when I look at him and as I check out he walks past me and disappears into the office. I feel bad, like I’ve freaked him out or something, but I don’t know how to make it up without making things worse. Should I just give up and leave the poor guy alone, or should I try a better way to show him I’m interested?
