you can go there and tell them you know me. maybe get a drink or 2. i actually bartended a little bit and i was only 19. i had my 20th birthday there and everyone thought i turned 22 (because they all thought i was 21 before that).
about the break, you'll probably have to work someone (in the mail room or something). i was pretty lucky because i went from one school to another without a big long break so i didn't have to do extra work.
