Ok, some things that are flummoxing my colleagues who have never left Africa. Some of which are expats and very high up in the organization:
1. Escalators - Can't get on em, can't got off em, totally freaked out.
2. Moving floors in airports - Much the same, only even more panic at the getting-off stage.
3. Elevators - I keep on coming across them standing at the bank of elevators waiting for one to come even though they haven't pushed the button (which we've explained, they just forget). They also don't push the button for the floor once they get in.
I'm honestly NOT saying these things to make fun, I'm not. I'm just always amazed at the things I forget are completely foreign.
