Funny you mentioned broken biscuits. At one time my old man worked at the Meredith & Drew biscuit warehouse in Stony Stratford, when we lived out that way.
On Saturday mornings as a little kid I got took into work (early work experience!), and almost every Saturday someone 'accidentally' knocked a high stack of biscuits over, being careful that nobody else was in the area first.
Blokes would come from all corners of the warehouse to view this disaster, and the chargehand would make out a 'scrap off' sheet, and then let everyone take a tin of biscuits home, usually for a few pence apiece. It was usually custard creams and the like to which this disaster occurred, oddly enough. No wonder my teeth were bad as a kid!
