Marlene, technically I'm a Production Assistant for the Locations department (depending on the show, I'm the prep PA, the set PA or the wrap PA - I prefer prep and set PAing because I get more things to do). In layman's terms, I'm the set whipping boy. Anything from "Vin Diesel wants a sandwich..." to "Can you negotiate with that location so we can film there tomorrow?" (The fly-by-the-seat-of-their-pants shows are the best for me because out of desperation, they're willing to throw responsibilities at me that would otherwise be reserved for higher-ups in the locations department).
And yeah, you guys are right about the cash in the back pocket thing. Normally I'm anal and stick it right in my wallet, but I just grabbed a few bills while I was running out the door, and *meant* to put them in my wallet when I got on set.

On the bright side, it must mean that my ass isn't so large that the bills were plastered to my cheek all day! (There has to be a bright side to this...this time 3 weeks ago, I was down to $8 in my account. Losing $30 like this KILL ME.)
