If you need a refund of £40 from a surrendered season ticket how is
this done at a passenger ticket machine even if a member of staff has
signed on?

Make weekly and monthly seasons non-refundable, and annual ones only
purchasable by card [how many people pay by cash?) and refundable only
by mailing them in.

Then announce that this is "progress".

Do you get 40 £1 coins rather than 2 £20 notes?

TfL machines are among the few places that give £2 coins as change.
