Think petard, hoist, own

The thing about Friday is it’s the day at the end of the working week (for most, until Labour brings in a 4-day week) and it last just 24 hours. Thus I don’t feel tempted to get involved in Black Friday sales on the ground that the people running them are too dim to grasp the concept of Friday. And mostly too crooked to offer genuine bargains, according to all the exposés.
