At a shopping centre in Bangkok, I asked for directions to the lavatory
“second floor sir”
For a moment, I paused, as my brain processed the information: “when she said ‘second floor’ what does she mean?”
The world is divided into different types of conventions regarding how to count the levels of buildings:
1. The Ground floor is numbered 1 and all subsequent floors follow. In this case my lavatory would be a short escalator ride up one floor.
2. The ground floor is labelled G, the floor above is 1 so my lavatory would be two levels up
3. The ground floor is labelled 0, the floor below is -1 and the floor above is 1
4. The countries with no standard system!!
It can cause mild confusion but is not usually an issue -unless one is in a hurry!
