then last saturday i went back in and she was in the back doing something she looked up and our eyes locked for like 20 seconds idk how long felt long then she came to the front and the chick who was putting cheese on my sandwich i couldn't concentrate cus i was looking at my crush but my crush asked the other girl what do you want me to do with this like i feel like she came out because she saw me, anyways then my crush started making my sandwhich an dshe was like how was and i said good you? then she asked me if i was taking classes at the college and i was like naw i'm in highschool and she was like oh i look older then i am and she was like "people always tell me i look younger then i am and how it'll be good when i'm 40, but i'm not 40 im seventeen lol" and i was like yeah no i go to the high school and she was like awh and she was like im gonna be a junior next year and i was like i'll be a freshman next year in college and she was like at University and i was like no Comunity and she was like oh cool my friend went there she really liked it. while we were talking she totally screwd up my sandwhich she looked kind of nervous i told her one squirt of mayo and mustard she put like three lol and forgot the tomatoes and i was like oh its all good. then a load of people came in and i was waiting for checkout and with them she was fine then she looks over at me and mouths a sorry to me and i give her smile it was okay then she comes to check me out and i give her my credit card while she slides it i point at her name tag trying to get her name (which i new already but ;) ) but she looks up and it looks like im pointing at her boobs so im like whats your name and she is like ----- and i was like mines ----- and she was like kooja? and i was like noo 00000 and she is like im gonna call u 0000 you get tht a lot? and im like all the time and she is like u want ur reciept and im like yes no no because im nervous and she is like enjoy so
