The appeal of the individual in the rattling van with a ladder on top who can slip you something dodgy for a monkey or a pony, and talks out of the side of his mouth, is lost in the North, where people are used to working or, in hard times, not working, en masse. The sole trader is suspicious on all counts: he never goes on strike ("I'd be cutting me own froat, mate"), he cannot be unemployed, since he has never actually been employed by anyone, and you don't know who his friends are, since he calls everybody "mate".
