Why why why try to enter an elevator before letting others exit?
You know, one sees - daily - instances of actions performed that suggest that those performing them are doing so for the very first time in their lives.
What else could explain the complete ignorance (utter lack of consideration?) of the consequences of something so fundamental as... trying to get on to an elevator at the same time as others are attempting to get off? (Say...)
Time and time and time again, I'll be the position of egressor (is that a word?) - the one getting off - and someone else waiting on that floor to get on... WILL NOT WAIT until I complete my obviously intended manoeuvre.
They'd rather barge in, against the current as it were, then - here's the niggly part - then react as if the resultant clash has never occurred anytime previously in their entire existence.
There's no answer, I know - but it doesn't stop me wondering how the HELL they can't see that simply allowing those who wish to, the space to get off, THEN stepping in - unimpeded - is the way to go.
And yet - despite the fact that that clash MUST have happened to them in the past - the practice persists.
Sigh - there is no rest for the rational.
