One particular thing I've seen many people doing is trying to touch-out
or touch-in on the wrong Oyster pads at station gatelines, where those
gatelines are unattended and hence left open - i.e. people leaving the
station don't look for the green arrow light to indicate that the gate
is an exit gate and instead try to touch-out on the inactive Oyster pad
on the wrong side of an entry gate is (or vice versa for people entering
a station and trying to use an inactive Oyster pad on an exit gate) -
also people walking through open gates before then remembering they need
to touch-out, but instead touching-in on Oyster pads on entry gates.
Part of the problem here can be that the lights on the gate's PED unit
(? - it stands for something that I can't recall off-hand) are sometimes
rather faint.

Oh! I had always assumed that there was no difference between entrance
and exit gates in this situation - ie the pads behave the same as those
at ungated stations, being used for both entry and exit. If the
situation is as Mizter T describes it ought to be publicised much more -
unattended gate lines are far from rare.
