In the specific example cited by @londonteacher*, isn't the most cost effective safe option to buy a ticket from Rainham to Chatham for about £5?
In what way can it then be claimed that the "correct" fare for the journey hasn't been paid? It clearly has, even if you don't actually waste your time pointlessly doubling back.
In a sane universe, a prosecutor trying to pursue someone through the courts in those circumstances would be mercilessly mocked by the presiding justice and then sent down to the cells overnight to "''ave a word wiv yerself m8". We don't live in a sane universe so there'll probably be a reason why even that is verboten.
