Ever Been Robbed Of Weed?

So who's been robbed of weed and if its not to touchy how did this unfold? Following the answer whats the best way to predict shits going down?

I got held up but they didnt get shit. This dude I deal with once in a while brought a buddy by, totally un announced, and asked if he could grab a qp. The guy has never bough more than a Half ounce before so i was kinda weary about it. But hungry for money i pulled out my big ol'sack and started weighing it out. after a few hand fus on the skale i relized the stranger had pulle dout a little .22 and pointed at me. "I'll be taking all that tree and any cash you got." I got a little nervous, but I carry a 9 and .45. So I pretended I was doing what he said i handed him the bag and said"Let me grab the cash, calm down man, i dont wanna get hurt." My 9 was in my back waist band, so wen i reached for my wallet, i grabed my piece and shoved it in his face and started flippin. I was pretty scared but apparently i was intimidating because he got scared and ran leaving the mutual friend standing there like an idiot. Just deal with people you know and trust and you'll have no worries.
