I had a puncture on my bike today that I couldn't fix till I got home so
had to use the District and Circle lines (only) to get from Putney to work
and from work to King' Cross.

Although East Putney ticket office was happy to top me up £1.80 for the
first journey, King's Cross (Western ticket hall) was utterly jobsworth
about the £5 minimum, even though I wanted the £1.80 top up to get a
receipt for the right amount. Are they all that inflexible in zone 1?
