Lift Etiquette

You know how it is; you are in a lift or about to enter one and someone is heading in the other direction.  Now in the UK there is a protocol for this sort of thing - I vaguely remember signs on the undergrounds saying something along the lines of 'Please allow passengers to alight before boarding'.  And in my day (I've entered middle age, so I'm allowed to say things like that) people in the UK generally complied.

In Nigeria things are, of course, different.  Three rules:

1.  When entering a lift, try to walk into the people exiting;

2.  When exiting a lift, gaze vaguely at unfamiliar surroundings wondering why it is not the ground floor.  Then re-enter the lift just before it continues downward thus inconveniencing everyone with an extra 5.3 seconds' delay;

3;.  Under no circumstances wash or use deoderant for 13 months prior to entering the lift.

OK, it's a gripe of mine, but to a certain extent I miss the superficial politeness of the UK.
