I'm 21 and I'd probably think he was a rad old stoner unless he came off like a stiff out to narc on the world. I guess the key would be to make a little light talk first then kind of ask off hand if anyone blazez bud, then just say how much you'd like to have some. with any luck, people will try and help you out, unless they're too paranoid and think your heat.
All I'm sayin is that if anybody i don't know asks me for weed, or where they can get some i pretend like i dont know what weed is... I would say the best bet is to make some friends, and then ask one of them if they have any, or any hookups because it's much easier on the nerves for everybody when you can say " Yeah i'm bobs friend, he told me to call you" or whatever than just asking the same dude without knwoing his friend bob.
