If it is, then it adds a nice feature to travelling to DLR and other
stations without the barriers. I can just go to Canary Wharf shopping
centre, buy some stuff, and go back, paying just 1 quid (i live in
Z2). Is there anything that can go wrong in this method? Any exception
from entering and exiting at the same station etc.?

If the ticket inspector stops you on the journey back they may get
suspicious about what you're playing at, although it's not clear if
they're likely to do anything about it.

And last question - is there any website I can check what exact fare
would I be charged when travelling between two stations? On some
journeys there is a choice of going through Z1 or not, and I would
like to know which of these applies on the particular journey.
