If you're travelling from an LU station to an NR or DLR station that

don't bother touching in or out at your destination. Just touch out at
your home station when you get back and you'll be charged the 4 quid
maximum single fare - less than for a return journey from most outer
stations.

Wouldn't that be eight squids rather than four?

Nope , it only deducts a single journey. Presumably thats the penalty
fare if you realise you've forgotten something on your way to work or
wherever and have to return home so touch in and out at the same
station.
