What a brilliant idea, we thought - everyone has to get their grumpiness out of the way within a specified time limit - say 6.30 to 7.30.
Work issues are always good for a grizzle. Lack of cash and the rising cost of living - everyone has opinions on this subject, however much or little disposable income they have. The latest stupidity of Him Indoors or Her Indoors is a bottomless well of stories.
Drivers - everyone else on the road is a blithering idiot.
Parents - what the little perisher did today.
You can bitch all you like - for Grumpy Hour - but after that, let there be no moaning at the bar!
