I'm signed up for the auto re-charge thingy - once your card has under £5
it adds £40 the next time you go to a tube station.

My balance is very low, and I'm unlikely to use the tube this week but
will need to use buses. If I go to the tube station and put my Oyster on a
gate (to recharge it) but don't travel, surely that will result in an
unresolved journey? Or can I 'charge' it on the big ticket machine, or ask
at the ticket window?

TIA,

Ian
