One thing that most people do manage to get right is the

Indeed. Another thing most people get right is letting people off the
train before trying to get on.

Most of those who don't get this right (seems to be more common on NR
than on the Underground) seem to be teenagers, and some even have the
gall to be offended when I insist on getting off first.
