Q. "Not surprised that an "undercover reporter" found the work difficult- he would not be used to any kind of physical labor."

He wasn't an undercover reporter in the normal usage of the term. He was in fact a very fit mountain runner whom Panorama had chosen especially for the job. If he found it hard going, then God help the rest of us.

Dave. Thanks for the reassurance about Morrisons. I have just switched to them, having been sickened off the behaviour of one of their major competitors. A number of people have pointed out that trying to be an ethical shopper in the present economic climate is like walking through a minefield. That is eminently true. But at least if you make the effort, you might fractionally improve things. You certainly won't if you don't.
