In reply to:
First you attack Spain, now National Slacker Day??
The UK and Spain have been attacking each other (both physically and verbally) for centuries, so any recent developments here are simply ongoing skirmishes in the much larger battlefront.
Re: National Slacker day, well apart from the fact that slacker is an American term, one could say that the English probably raised slacker-dom to a fine art form even before the 13 original colonies in North America were formed.
And recent innovations in the last 100 years included the Trade Union movement and feather-bedding practices.
However, that would be a little unkind to point this out :-)
The average British worker generally does not need any externally imposed reasons from some [presumably American companies] 'marketing' department to stay at home from work.
A bit of snow can do that without needing to pre-arrange it in advance [especiallty if the workers concerned work for the UK Railways or any UK public transport].
Still I am sure the hard working Cambridge based employees of SB did not slack any more or less than they usually would last Friday :-)))
