I met a guy from here once. He asked me to get him weed a few times. I haven't spoke to him in months. He probably found it elsewhere so he didn't have to pay a middleman, which is completly understandable. I had no problems with him, but I was cautious when he first asked me. I was very careful the first time getting for him. No one busted me so I had no problems after that.

You just have to be careful at first. Ask questions and see if anything is sketchy. All you can do is say no.
