The older trains operating on the District, Piccidilly and Circle lines
are
operated by the Train Operator (the driver to us mere mortals). S/he can
only open all the doors on the train together, there is no option to
reopen
a specific car. Hence when some thoughtless wazzock puts their foot in the
door, and the driver is in a good mood, s/he has no option but to reopen
all
the doors together.

It's much more fun when the driver is *not* in a good mood and makes a PA
announcement to embarrass the miscreant, whilst refusing to open the doors.
If you're in the affected car then it is even more fun watching as the other
passengers form a lynch mob.
