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

Hello first time poster here we go. so I've been going to my local Dunkin donuts fairly regularly ( 2-3x a week ) for the past two months. And against my better judgement I've developed a crush on one the girls that works there( I'm 22 and she is 19-21 if that matters ). And trust me I know the whole " its her job to be nice  thing" this is the 1st time I've crushed on some in the service industry and I don't fall for every girl that's nice to me. 
   
 She always seemed genuinely excited to see me( she always has one of the most beautiful smiles on that would just brighten up your day like it does mine). she would even smile and wave at me while she was dealing with other customers ( unfortunately her co-workers would take my order before I got to her on numerous occasions :/ ). One time when it was just her up front, she told me she was glad I walked in ( in probably the sweetest voice I've ever heard ). She also would say goodbye/ have a great day even when others took my order and she was busy. Early in my time of going she asked what my name was and I told and I asked what her was. she brought one of coworkers over and introduced me as her friend.
Unfortunately the last 2 weeks or so she working the drive-tru because of new hires/promotion maybe and we only been able to get a quick "hey" in. when i did get to talk/see her I tended to be nervous but I always had some big cheesy-ass smile on 

I haven't to decided if I should she ask her out/ leave my number yet  should I  get a chance to talk to her.I don't want to put her the spot. I've read on other forums that this makes girls that it makes feel really uncomfortable and feel forced to say yes.
    But on the other hand I really want to get to know this girl.
     Advice? Should just hope she comes back the front lobby?, start going to the drive-tru, just give up?
