Sir; Is there any hope that in the course of giving shopping trolleys minds of their own' (The Grocer, June 1, p40) the anoraks will equip these innocent little machines with some form of anti-dumping device?
An ear-piercing squeal, or one of those horrid mechanical voices repeating ever more loudly "I'm being abandoned, I'm being abandoned", triggered when the trolley is taken beyond a short distance from its home store and only to be silenced when it is returned, would do very nicely.
In King's Lynn, supermarket capital of the world (everything bar Waitrose) we might then hope for a reduction in the fleets of trolleys disconsolately awaiting collection all around the town and be spared the sad sight of the mud-caked, broken corpses of those unlucky enough to have fallen into the hands of the King's Lynn vandals before ending their days in one of our various rivers and streams.
Seemingly, trolley pollution can't be prevented by pleading, bribing or fining. Electronic embarrassment might just work.
