Search Results: girl suddenly stops talking to me

Okay so I'm a Cashier. And there was a guy who helped me bag on a busy day. He works in one of the back departments though so our paths had NEVER crossed before this.
Now usually I personally HATE when people try to help me bag. Like I never say anything, and I do genuinely appreciate them trying to help. But I always feel like I'm being slowed down because I have to wait for them to get things in the bag after I scan things because it's a lot faster to just scan something than actually put it in the bag. Not with this guy. We somehow found a pretty good pattern after just a couple minutes of working together.

After that day, even though I'd NEVER seen him before, suddenly I see him almost every day. When he goes to use bathroom, he uses the front ones now, where as the department he works at is closer to the back ones. He comes to front during his breaks now. He's winked at me before, and occasionally makes a face at me while I'm working to make me laugh. Before he leaves, he stops by my register and holds my hand for a moment. Today he even came to MY register to check out some groceries. And I was honestly THRILLED about it. But I was doing that like "Be cool" thing in my head. Until it was his turn that is and then he was just standing there making me laugh my little butt off. I was grinning for HOURS after he'd gone home. But I mention that because, it wasn't busy, he could have gone to any other register and gotten the same wait.

And another time, he had said good-bye to me, and then like an hour later I saw him again while I was pushing carts to customer service. And his mother works up front with me, and I smiled at the dude, he smiled and winked right at me. His mother was like "I SEE YOU FLIRTING" to him, and I was like "I thought you left an hour ago". He told me that something had come up, and his mother was like "A girl! A girl hold him up!" and he got all red and left then. But I don't actually know if she was talking about me or not.
Opinions?
