How does your city number high-rise floors?

[Doug]

A potentially fun thread....

I've notice some patterns in how building owners assign numbers to floors in their buildings, that often considers cultural biases. For example:

-in the US and the Canadian province of Alberta, most buildings skip floor 13 as the number is considered unlucky. The real floor thirteen is named "14". See this in other parts of Canada, but not as ubiquitous as in Alberta
-in China, owners typically skip floors ending in 4, again because 4 is unlucky. See that in some buildings in Vancouver and Melbourne
-in Canada and the US, the bottom floor is typically named "G" or "M" for "Ground" or "Main". The next floor up is 2. In much of the rest of the world, the next floor up from "Ground" would be 1
