The part I don't understand is why they do this in the first place. I
thought the LU system is rather "fraud safe". You can't get in or out
of the system without some form of valid ticket (except by climbing
over the gates or taking a detour to a DLR station), so hunting down
fare dodgers should be pointless. What am I missing?


Several times I've been caught by this trick, so perhaps they watch for
it. Everyone hurtles up to the barrier and the person in front of you
offers up their ticket / card. They start striding through the barrier
and you follow up behind and put your Oyster on the reader, just as they
get the "seek assistance" screen. They carry on through (on your card)
and you get left there looking like a lemon.

I now hold back and wait for the person in front to fully exit the
barrier before I put my Oyster anywhere near the reader. On two
occasions I've had people with the "seek assistance" screen look back at
me, and look at my card.... obviously waiting to be let out. Oh no, now
I just glare at them until they go elsewhere.

Then you still get the people who try to keep about an inch away from
you and go through the barrier on your ticket. All extremely annoying
and I'd like to see a few of them named and shamed on bill boards
outside the stations. One main cause of this is the train routes (like
the old WAGN line into Moorgate) where there are still no barriers to
entry or exit !!
