Junkies
When you see a man teetering on the sidewalk, his eyes shifting like crazy ... Yep, no doubt about it, the skinny geezer is strung out on some chemical concoction with a long name, more commonly referred to as drugs. The hard stuff, that is.
Junkies hang out in the Amsterdam Underground stations and roam the streets of the Red Light District. Most of them are quite harmless. Their drug habit has ruined their physical strength. Dope isn't cheap in Amsterdam, so stealing bikes and smashing in the windows of a car to get at the valuables inside has become a routine. Female junkies offer their rattling frame for doubtful sexual purposes.
The locals ignore the junkies as much as possible. They are a nuisance, and occasionally they end up in one of the canals, when caught red handed at stealing a bike. The police round them up every now and then, but since there are not enough cells to keep them in, most of them are back on the streets in a matter of hours.
If you get fucked, hassled, robbed or what have you, by a junkie, go to the police. You will be handed a form for your insurance company and be invited to have a look at some mug shots. It's amazing how much the losers look alike.
