Ah, so it seems they have calculated the fare owed on the basis of
daily tickets [1] and given no "discount" for the use of seasons

I make it about £37/day, which is close enough to their figure of £19.80
each way (at today's prices). It appears he's not getting a 'credit' for
his £7.60 a day TfL max fare.

?would he be charged a second £7.60 for the unresolved journey back
home?
