i think it would more depend on how hard it is to get and how risky.....cuz if you were my friend and it was impossible to get i'd beat your ass. (assuming i was dumb enough to leave my stuff at a friend's house..) and if it was a big risk (driving long distances in cars, being around shifty neighboor hoods and people...etc...etc....etc....) i would make you go buy it and if it didn't atleast weigh out when you got back.....again i'd beat your ass...that's just me tho like home dude said
