Seen on a notice at a Cambridge Cafe:

Waipa District Council. Permit to occupy pavement space. This is to certify that **** has been approved to occupy 15.000000 metres squared of pavement space.

I might not have got the exact words right, but I certainly counted the number of zeros after the decimal point.

The cafe will be delighted, I'm sure, to know they can occupy 15.000000 metres squared of space as opposed to 14.999999. That extra square millimetre will make all the difference to their before-tax annual profit. Perhaps they'll be disappointed they hadn't applied for 15.000001 metres squared.

Presumably Waipa District Council, when they come round to check that this cafe is abiding by the rules of its various permits, will be measuring each linear dimension of the tables and chairs to the nearest millimetre.
