The shops fill with Jekyll and Hyde characters, alter egos of the normal placid human beings they once were before they were faced with the inevitable truth.
Babes and toddlers have been left in the care of Nannas and Grampies for their own safety. Chaos and mayhem ensue as battles of wits and language are exchanged with frightening ferocity in the confines of such limited space.
Outside, the snarl of engines and shortened tempers blare and scream in contempt and competition. Occasionally the shatter of glass breaks through the cacophony of frustration and a different tirade of abuse takes precedent.

Get out of the way before you are flattened by a speeding trolley under the control of some desperate creature who has suddenly realised there is but one day left.

Baskets are discarded in favour of trolleys, fights break out over custody of the last as the clock ticks merrily and mercilessly forward.
Early closing is bad enough.
But the fact that the supermarkets are closed on Christmas Day has millions panicking, stock piling, and giving company share holders probably the biggest High of the year!
