Oldfarmer,
I have to agree with you, it is all probably just a passing phase.
A friend has just bought one of those new fangled 'Superposed'he's just back of holiday by Lake Garda and keeps muttering 'Sovro Posto' but he'll get better once I've got some Faggot & Peas into him.
I believe we drive on the correct side of the road to allow our loved ones to alight onto the pavement rather than into oncoming traffic.
Americans drive on the right because we know they screw everything up.
Including putting barrels back on the face.
Gunman,
It is my belief that the term 'water table' comes from a surveying term dating back to Egyptian times.
Where datum points were taken from 'the water table' because it was a level surface.
I think the American originator chose the word to illustrate the 'datum point' where measurements were struck off from and information was stamped.
