Gigging overseas aside, not taking your own kit to a gig is simply lazy. I wouldn't let anyone use my rig, and no-one ever gets near my bass. And there are and always will be, no exceptions to that. A band with no gear is no band. My experience on asking these folks where their gig money gets spent is normally fags/booze/women. Try spending it on kit and some wheels. You might actually get somewhere that way...
As you can tell, this is a subject that bugs me royally...
