Then you should take the next three Mondays off.
Tell them you are doing research for a multi-million dollar American organization on the ratio between beer and the minimum wage.
The only thing that's not true is the multi-million dollar part
and that I'm not really an organization,
but I am American.
On second thought, maybe mentioning minimum wage isn't a good idea.
Next Monday, why don't I call them for you? I could say you'll be in Tuesday IF you feel like it and IF they don't like it, well, that's just too bad.
How would that be?
