An Anytime return would be far better value than ^59 + CIV▸ !
Not neccessarily.
I've purchased a ^59 Eurostar ticket before now just in order to be able to buy a ^50 Bath - London CIV valid for peak time travel rather than a ^130 ish Open return. I've used the Eurostar ticket on one occassion (a free weekend in Paris) and thrown it away on another
If that is "abuse" then I am guilty.
(All this talk of "abuse" reminds me of a 20-year old Les Dennis joke along the lines of "my mother is so stupid, she thought she was cheating British Rail by buying a return ticket and not coming back"
