<human>: Give me a shortened version of the text

Hi! About a month ago I went to a used bookstore. I asked for help to find a book to the cute salesman and we talked for a while about Game of Thrones. He is a massive fan and the discussion was really interesting. I love intelligent men and he seems to be very cultivated! He also sings with a beautiful deep voice (I heard him sing along with the radio playing in the shop)!

 He works alone there so everytime a client wanted to pay I just walked away browsing the books, and after he would join me again to continue our discussion. I returned to the shop a week later and he recognised me so I was happy! I was with a friend then so I didn't really talk to him, just said hello. But this week I returned again and we talked about GoT during 20-30 min!
 
Then I returned the next day with the firm intention of asking him out, I even practised what to say in front of the mirror, I checked on the web for advice and I was all pumped with courage and confidance....till I entered the shop and saw him. I just said "hello" and browsed the books without conviction. We talked again about GoT (he really is a walking encyclopedia about this subject!!) and then when I realised I would never have the balls to ask him I left.
 Help me!! What should I do? I don't know if he is also interested in me or if he is only passionate because we discuss about his favorite book/tv show. Also I am at his work place so maybe he is just polite and doesn't really like me but has to pretend to be interested because I'm a client. Should I ask a close friend to go ask him out for me (feels like a school girl thing to do, not a grown woman's option), should I just never go back to the shop because I made a fool of myself by going 2 days in a row? (it's so obvious now that I like him)? Sorry for my poor English!
<bot>: met a cute salesman, too shy to ask him out, but still can't stop thinking about him, what should I do?
