Not that unbelievable. I've seen it... scoffed at it... then smoked it and understood... still wouldn't pay for it cause I'm too cheap.
Anyway... I've been ripped off a couple of times, but flat out robbed only once.
The year: 1999 location: alley of NYC
This really happened... cross my heart!
This freakin head case sells me an 8-ball. Transaction complete. I put the goods in my pocket. I attempt to hit the road figuring I'd readjust my shit else where. I turn to pass him and the motherfucker is cutting HIS hand open with a tiny pocket knife!!! He threatens to give me HIV if I don't give him his coke back. I stare for a moment dumbfounded as I rip open the bag in my pocket and fling it at his face trying to be all ninja style... But I missed. It went over his shoulder and landed perfectly on the ground behind him without spilling a drop. 
he turns his head and I bolt out of the ally never looking back. I get back on the subway and lick what little coke is on my finger from ripping the bag open. It turns out to be baking soda.
Somewhere... there must have been someone filming that transaction for some ghetto-style candid camera. There is no other explanation for it.
Haha.. You realise that unless he forcefully got the blood in a cut or your ass, nothing wouldve happened... I wouldve just told him to fuck off before I beat him down.. I also woulda made it clear that he would probably get an infection, which happens to be fatal for HIV+ people...
Or I would walked off.
Or I woulda said I was HIV positive too, and that for trying to pull this stunt, Im gonna make him my bitch.. Hed prolly leave after that..

Sucks about the gear though..
For the most part, those who get ripped off, are those who project the appearance that they are easy to rip off... To minumise this, know your shit, and generally act like an asshole.. Acting like an asshole in legit buisness will get you a lower quality product, but there are no rules in the drug buisness.. Make it apparent that you dont fuck around.. Of course this is all solved if you buy from people you know, that are friendly.. By asshole, I dont mean freak out and insult your dealer.. That would be bad.. More.. Be straight forward with transactions... Be quick and make sure you hold 2/3s of the conversation.. Dont wavier on prices too much..
Also, it is common knowlege that the drugs are always exhanged before the money.. If your dealer asks otherwise, he is either gonna fuck you, or is unsure about his product's quality... Both are bad.. Always get ahold of whatever you are buy, hand feel the weight, and look/smell/taste. Dont go to thourough, cuz youll get shot.. But your inspection should take 20-30 seconds.. Then give the dude your money, say thanks, and walk away.. Alot of trouble comes from haning around. Of course all this is to be done with moderation, or you could get shot for acting suspicious. Act hard, but not shifty... Pull out your money to show you are legit.. if you do end up talking around, implying you deal, even if you dont, will make other dealers less apt tp screw you over.
Never pull out more than you want to spend, as dealers see this and will quote a higher price... Also, if I have $50 on me, but only want to spend $30, Ill leave the 30 in my wallet and put 20 ion my back pocket... Then when he quotes $35, i can pull out my wallet and show him that all I have is 30... I have yet to find someone who says, come back when you have the extra money.. Its not worth the hassle, as long as you skim off the top of the price...
As for getting ripped off.. Im careful, and have only really bought fake E.
I had a friend though that went to spend $700 on a half pound of weed.. They met in an apartment complex, and like a jackass my friend gave him the money first.. He said he had to go to Apartement 11 to grab it, and just to wait there.. Turns out the apartments only went up to 10... Cant say I blame the dude though.. The drug buisness is built on criminality... So if a dumbfuck is stupid enough to be ripped off like that..... Well it makes more sense to steal it and save product.
