Due to Southern cancellations used Tulse Hill rather than my normal
Streatham Hill, from Canary Wharf, via Canada Water. Asked for a refund
after being charged £2.00 exiting Tulse Hill and TfL Oystercard operator
told me this was only a goodwill gesture and would not longer happen
again. Seems the fare is defined to Streatham Hill but not to Tulse Hill,
so you get charged at the latter. Since I haven't gone outside my zones 2
and 3 I don't understand the charge.

I think what they meant was that there isn't a fare defined to Tulse Hill
that avoids zone 1 by changing (using the routeing validator) at Canada
Water.

Canary Wharf to Streatham does have two fares defined - so you must normally
be using the pink routing validator?

This is a commonly reported feature - the route validators do not work for
every possible A-B pair, only those that have been deemed likely to be used.

The solution must be a means of formally proposing that a new 'not Z1' fare
be created which needs a routeing validator touch somewhere.
