Was the Ticket Office unstaffed Annabel? Sometimes the people there are
quite helpful...

There was a queue, and I was in a hurry. Only took longer than I meant
trying to see if I could do the two things at once (I've been caught by
the "card" thing before).

I agree it should be possible to do more than onr thing to an Oyster
Card though.
(I have sometimes used a credit card for one item and a debit card for
another though)

So have I, but I'd rather do one payment for both.
