Have farmers gone off their trolleys?

Afraid that farmers might have all the trolleys chained up, she turned to me in her hour of need.
“Of course I will,” says I, putting on the transport box to the back of the tractor. A fellow needs no shopping trolley when he has a transport box. And, later, with the shopping done, I turned to leave the supermarket car park, only to spot a herd of protesting farmers chained up to a trolley bay.
