my friend recently went into a local Discount Smoke, a cheap glass shop, while my friend was in there the foreign guy behind the counter tried to sell him a mini butane torch saying it gets so hot it can melt glass he then apparently wipped out a meth pipe and lit the lighter underneath and says "look now two hole" this has to be soft glass is he seriously slanging this to stoners or fucking with meth heads haha
It goes farther than personal experience, glass shops (not good ones) all over the country could be doing this
I went into one afew months back and the guy acted like a used car saleman. He pull's out a china made glass pipe and throws it on the floor to show me it wouldn't break i still said no thanks...lol.
this is why I buy all my shit from the GCstore or my LHS..... unless I am buying a BIC lighter. Too much sketchy crap out there sold by sketchy people.
