Nope, they have them at both the local Tesco's and Sainsbury's here. I'm
ashamed to say that my friend does this for a living. Although I must say,
he rather enjoys driving around on his little buggy! Not in winter though.
Too cold.

(Horridmarket shopping trolleys)

They have spend a lot of money on them. They need to be built to take
heavy loads and give a smooth and quiet push for the customer. Lots of
design work has gone into those things over the years trying to develop
them so they don't get wobbly wheels after a few months of abuse and
don't end up turning left constantly.

I'm tempted to say something very rude here. Little if any informed
design work has gone into them, especially in the undercarriage area.

I was writing to supermarkets back in the 'sixties and 'seventies
pointing out that wheel-wobble, flapping, etc requires only a slight
adjustment in the angle of the castor mounting shanks to eliminate those
vices.

The castors are still mounted vertically.

The supermarkets are aware that while price is a factor, they *will*
lose customers for silly things like too many wobbly trolleys. That they
spend so much on bearings and design has led them to try any number of
means of retaining their property. The initial attempt of making you put
a quid deposit in the trolley was unpopular with many and is
disappearing slowly. The new trolleys are more expensive since the
wheels became a little more high tech and when you cross the boundary of
many of the supermarket sites, a brake mechanism engages.

And the castors are still mounted vertically.

These new trolleys have their own problems in that sometimes they'll be
scooped up by the low-wage trolley collectors with their electric
trolley pushing machines and forced across the entire carpark,
developing a flat spot on the braked wheel.

Those eclectic trolling chamines have yet to hit us here in rural East
Angular.
