The guy who drove his forklift straight through the portacabin wall and the guy who was found outside the compound semi-conscious and coughing blood had this in common - both were blind drunk, on cheap aftershave. Subsequent inspection of the workers' quarters showed that most had a large bottle of the same cheap aftershave tucked away somewhere. All were of course confiscated on the spot, as if that were addressing the problem.
How about, instead, providing an affordable 'clubhouse' bar where the guys could have a beer or two after work? How about raising wages to the level where an occasional visit to a cheaper hotel bar is a reasonable prospect? Oh wait, we've closed all but four and five star outlets haven't we, and we're working on closing even the fours. Better still, how about allowing the workers to bring their families to Qatar? Of course, Qatar is not good for women and children, because of the grossly skewed male/female balance. But isn't that a 'problem' that presents its own solution?
In short, how about respecting the people who are building your bright new city?
Now back to the aftershave. Those of us who can afford our preferred tipple might look down on anyone who would raise a bottle of aftershave to his lips. But we'd do well to remember that all strong drink is an acquired taste. A child presented with whisky and aftershave would find both equally repugnant but might even favour the latter, for its nicer smell. (This is a thought experiment only, of course!) Remember too, that these guys are not the old-style western down-and-outs whose addiction has so degraded them that methylated spirits or even brasso is their final port of refuge. They are workers, though they might as well be slaves. What they do, they do from desperation. It is wholly avoidable, and that's the shame of it.
