When I entered a shop the owner stared at me for about 10 seconds. Does this mean anything?

I'm curious about a shop owner that stared when I entered his shop for a very long time. I tried to mind my own business. He seems to enjoy teasing me a bit and is very friendly. It's a bit weird as I'm only 23 and he is easily 50. I also found out he has a wife so I now avoid this shop
