Safety and customer service. That's it. Problem solving, management, no headaches for the GM. Safety is good, climbing 5.13...who cares. Cleaning the pizza off the floor after the party, that's the value you'll bring. Ask the GM what he/she thinks is most important and parrot that back. Ask lots of questions if you can. People like to talk about how great they are, if you can get her/him talking, the battles half won.
