"Ok, here's the deal"

"You help out in classes, be the extra pair of hands showing guys how to get the mag release button and the safety out of the gun, and I'll let you use the machinery in here.  Hell, I'll closely supervise and teach you how to use the machinery in here.  Don't embarrass me."

DEAL!

Here's the thing...  This way I get to take the classes again FOR FREE.  It's review, yes, but I always learn something new.
