Trolleys 81a and 81b

It is turning into a bumper week, with two more trolleys turning up after the return of trolley 80, with these two being just off-site and both having been immobilised by their security devices, one of which is visible bottom right.

Quite difficult to push in this condition, so I contented myself with just pushing them back, one at a time, to just inside the Sainsbury's car park, from where the Sainsbury's trolley jockeys can take over. Do they carry a natty little tool to unlock them, or do the trolleys have to be returned to their shed?

See reference 1, for my first encounter with an activated security device.

I decided against scoring two further trolleys, the smaller variety, as they were only inches over the boundary, and clearly visible to a trolley jockey inside the boundary.
