What struck me about this exchange was the extent to which it revealed a widening disconnect between the haves and have nots, on the level of morals as well as income, exacerbated by the recession and the current government's policy of making the poor pay for an economic mess effectively created by the greed of the rich.
None of this was necessary. None of it was inevitable. Much of it is a direct consequence of policies introduced by one of the most ruthless and callous governments this country has ever seen. And for that same government to turn around and celebrate the charities forced to pick up the pieces is not only paradoxical - it's an act of gross hypocrisy.
I talked to a constituent who had a stroke and is on benefit. After paying all his bills, he's left with just £12 a week - less than £2 a day - to spend on food. In the new year, thanks to the government's so called welfare "reforms", his housing benefit will be reduced - by £12 a week. He will have nothing at all left to pay for food.
Last week Vickie and Mathew, a working couple, were helped by the foodbank. Their finances were stretched to breaking point after they had been made redundant from well-paid jobs and were forced to take low-paid ones instead. They've sold everything that they can and Vickie had gone without food for four days before she was referred to the foodbank by a children's centre. She told us that they can't afford any Christmas presents for their two young children, so she's been hiding some of their toys to give them something to unwrap on Christmas day.
