MIG: So are you saying for specific stations you don't get penalised
for entering and leaving the same barriers but for others you would?

You never get penalised if you are using a travelcard, on paper or
Oyster. The question was about the time limit that stops you turning
round and going immediately back through the same gateline (with a
travelcard).

When the travelcard is on Oyster, it doesn't seem to be a problem.
When the travelcared is on paper, there is a time limit. You aren't
penalised; it simply won't open the gate for a while.

I've never been able to work out any possible scam that would involve
putting a ticket through the gate twice (as opposed to just passing it
to someone) so I can't understand this restriction. For travelcards
on Oyster, common sense seems to apply and this restriction hasn't
been programmed in.
