Yeah - don't let it goto your head.
You don't know how many tw@ts there are doing Dispatch for the handling agents who think they know it all after 5 mins in the job and lord it around on the ramp and speak to people like cr@p.
Treat everyone as you would expect to be treated yourself - (respect is earned not a god given right) and you will get people to do a hell of a lot more for you if you don't go throwing your weight around and barking orders at people. There are a lot of tough loaders out on the ramp.
Oh and NEVER run EVER. Makes you look like you are out of control of the situation, and you don't get paid enough to break a sweat. The only exception to this is if it's YOUR f*!K up your trying to sort out.
Most of all though, have fun.
