Why don't the machines allow you to specify how much credit you want to
add and e.g. give change from cash? To add £6 to my Oyster to cover my
journeys on Tuesday/Wednesday I had to do a £5 credit card transaction
and then put a £1 coin in. If I'd have put a £10 note in, the smallest I
had on me, it would have insisted on adding it all the Oyster. In the
end I didn't even need the whole £6 so I now have some credit I probably
won't use for months.

You could select "Top-up pre-pay", then select enter amount, then enter £6,
put in £10, and get £4 change. I've even seen American tourists do it, so
it can't be that hard. (joke).

This is not an option on any Tube ticket machine I've ever seen. (I
even checked on my local one when I used it today.)
