I had the same problem Tyler, you just need to suck it up and put yourself out there. I, like yourself am really shy too so i know how hard it is. A good thing to say is: "Hi, i'm looking for a job and would like to work here, can i hand my resume (or w/e you might call it) in? Also if you do end up handing your resume in, the manager may be the one you hand it to. (it has happened to me in the past) In that case, introduce yourself (they like to see confident people) They may even give you an interview on the spot then. So you need to be prepared for that.
