How did you find a reliable dealer?

I know this is a silly question. Most people say through friends or just asking around, but I've had no luck finding someone who isn't a total scumbag. The guy I used to buy from I stopped going to cause he we really touchy-feely, and always made moves on me. I don't wanna feel like I'm going to get raped every time I pick up. And the last guy I bought from, who I though was my friend, ripped me off a lot. Like not even .5 short or something I could overlook, but a good 3 grams short. Its pretty annoying cause as girl who doesn't look like the typical stoner everyone I have tried to buy from either tries to get me to sleep with them or thinks I don't know when I'm being ripped off and tries to short me. So anyway, thought I'd ask how some of you met your reliable dealers. Maybe the same strategy would work for me.
