THE PROCESS WOULD REALLY BE QUITE SIMPLE IF PEOPLE WEREN'T SO "SUE-HAPPY":
1) Browse through the book.
2) Find a sign you like.
3) Rip it out.
4) JUST ADD TAPE.
5) Apply the sign to a drive-thru speaker.
6) Sit back and watch the fun (and madness) begin.
HOWEVER, SINCE PEOPLE ARE KINDA "SUE-HAPPY", PLEASE LEAVE ALL SIGNS BOUND IN THE BOOK AND JUST IMAGINE...
