I live in a country where we call the floor of a building at the ground level the 1st floor, the next one - the 2nd floor and so on. We have the same numeration in our lifts and these numbers are written on each floor’s walls. I learn British English and we are taught to say ground floor and so on about our buildings. Although, it doesn’t add up for me.
When I describe a situation in a lift, for example:
I live on the first floor, so could you, please, press number 2 for me.
It looks wrong. The same way it’s hard for me to say that I live on the first floor to a foreigner, especially if he is about to visit, because the numbers say 2nd.
Could you, please, tell me what you would say, if you were in a country like mine. Would you use your traditional floor numeration or would you use the numeration accepted in the country (especially I’m interested what you would say if you were staying at a hotel or taking a lift).
