Hardly. The OP is travelling with an Oyster card, using it as
instructed. The correct fare is by definition the one that is charged,
so long as he/she has touched in and out as required.

I believe the term is Estoppell - the system has collected a fare for the
journey and given the impression that it's correct. Once this happens,
they cannot then claim a greater amount from the OP.

[Warning: vague memories ahead] The original version of estoppel was a
rent case. For some years the landlord of a property accepted a lower rent
from the tenant than was actually due, signing the rent book each week or
banking the cheque or whatever. At a later date he then tried to claim the
difference back. Lord Denning said that he was unable to because he'd left
the tenant with the impression that the rent had been paid and accepted.

For the last couple of years, we in this group have been discussing the
anomalies in the oyster system and how to get it to charge the "correct"
fare. However this thread has turned the conventional wisdom on its head. So
if u touch in and touch out, it is up to the system to charge the correct
fare, so there can be no "oyster fare evasion". Take for example me,
arriving at Heathrow for the 2012 Olympics (along with a million others). I
haven't read this group, and know nothing of the zones, or of the
complication of transferring to the DLR. I get an oyster card and put £60 on
the card. All I know is, that I have to touch in and touch out regardless of
the erratic journey I may make (not intentional, but lost). As I speak
English (sort of) I will be less lost than the non English speakers!. So I
hope that all this is sorted and simplified by 2012

Sydney (you could do what we did in 2000-- run the system at peak rate
24 hours a day and free travel, saved a lot of confusion!)
