Guy's Behavior

Is this stranger interested in me or no?

I went to the store once with my mom and grandma this worker did a double take of me and was looking at where ever I went. When we went to pay he was trying to look at me and he was smiling. A week and a half went by and I went back with my mom to make a money order. He looked at me while ringing up some guy and he smiled at me that even my mom noticed it. Another week went by and I went by myself and when I was in line I saw him walking in the store and he saw me. He opened up his line fast and said he can help people in line. He kept looking at me when saying it even when this other lady behind me was walking to him. He smiled at me and said hi and also bye.

I went again friday, I bought snacks and I went in his line. he smiled and said "juunkk food" and asked how I was doing. I had to go back and I went in his line again. He was smiling and asked " are yooouu surree you don't want anything else?" I said no and he asked again and when I said no again he said "you'll be back again". I was to buy a bucket my grandma forgot to tell me to buy and his register was messed up so he had to go do something and his manager rang me up but that guy kept looking at me. Yesterday I went and he kept staring and when I went in the other line since he went to go something I was on the phone and saw him walking fast and he was looking and smiling and said "hey" so I said hi and smiled. The worker who rang me up and his manager were there so I didn't look at him again and he left.

Is he interested me and if so is there a chance he will ask my name or number?
