I was talking to one of the people on the produce department, and this was when they made the second reduction. On one occasion he saw someone grab a load of stuff after the first reduction - effectively reserving them for when the second reduction came along and saying "Oh you missed that one", but the chap refused to reduce them since he'd been holding on to them. The customer, not happy his master plan had been thwarted, threw the stuff back on the shelf and walked off.
