Just a quick note to remind you that in some foreign countries, the floor numbering of multi-story public buildings (like hotels and offices) may not be the same as it is in the USA.
When I was in Mexico last week, I checked into my hotel. The desk clerk explained (in perfect English) that my room was on the first floor and pointed me towards the building where the room was located.
I wandered all around the first floor and couldn’t find my room number. Then I saw this sign,
My room was on the first floor…the first floor up from the “ground floor.” In America, we would have said that my room was on the “second floor.” I’ve experienced this in several South American and European countries as well.
