there's been a lot of good input here, and any one of these responses could easily describe the reaction of the headshop proprietor. it's pretty unpredictable, but it usually is when you're doing cold calls to locate a source. however, you're not going to get busted for asking anyone about weed. you could even try to talk to a cop about high-traffic areas and as long as he wasn't undercover and you bought it from him, he couldn't bust you. I know no one's going to talk to a cop; it was just an example.

I'd recommend talking to a homeless person. it worked quickly for me when I was dry. the advantages are abundant: they don't have anything to lose, most of them are not paranoid because they know how the streets work, they generally ask very little in return. the only obstacle it seems is understanding the crack-induced drivel that they call language.

IMPORTANT: walk by a guy that's asking for spare change, give him a dollar, and ask for his help. an undercover cop won't be asking for spare change since it's technically illegal. undercovers aren't allowed to come up to you, you have to approach them with your proposal otherwise it's entrapment or something
