<human>: I met this guy who works at a local store and immediately we smiled at each other and struck up a conversation.  He asked how long I lived in the area and explained he was new to the area and we chatted for about another 5 minutes.  

I returned to the same store today to pick up something and he was there.  I noticed he was across the store when I walked in and within a minute he was by me and asked if I needed any help. I said "Hello again!" with a big smile and we stayed talking for about 10 minutes.  He seemed a little fidgety, like moving his feet around while we were talking and we kept smiling and laughing.  He is really cute, but I'm a bit shy to ask if he has a girlfriend or wants to hang out.  

How can I tell if he might be interested in me? I don't need to go to the store again, but I almost want to just to check him out! How should I approach this? 

Thanks for any advice.

Can you give me a shortened version of the text?
<bot>: Met a guy, we've struck up a conversation twice, but how can I tell if he is really interested in me?
