and don't be surprised or take it personal if s/he hangs up on you. i never heard of anyone doing biz with a stranger and a phone call..."hey dude, you don't know me but joe sent me...no worries, i'm cool"
just sounds way too sketchy to actually work in real life. and most likely 'joe' would be shut off too for being so stupid to pass out private info like that...but maybe things have changed, i dunno...
