"Did the guard sell them a ticket? If so, they were treated by the guard in an identical way to the OP, ie no ticket was presented and a ticket was sold, presumably at the Anytime rate.
The passengers you refer to were not charged a PF but neither was the OP in this case. Guards on SWT services cannot issue PFs."
They had no tickets at all (or presented no tickets to the gateline attendant). A couple of trains has just arrived so the attendants were busy letting people come and go. He drew their attention to the Penalty Fares notice on the side of the kiosk on The Mayflower Theatre side whilst letting people come and gotr and then told them they needed to buy a ticket before travelling in future and opened the gate and let them through. No tickets were sold at the time.
"The quality of gateline staff is inconsistent. Some are absolutely brilliant, friendly, and knowledgeable. Some less so unfortunately."
Seems this is also the case with a fair few number of rail staff and then leaving customers in the lurch making statements to which they are not entitled.
A few threads on here and what I saw at Southampton Central station this evening really does indicate how rubbish our ticketing system is and our Train Operating Companies.
I have a good mind to report the matter to South West Trains and asking them when I would be allowed to travel without a ticket but could almost write their fob off response myself.
What do you suggest should happen in these sorts of cases? Prosecution of those without a ticket?
I'd suggest rereading the thread, there is a lot of patronising replies. Some of your replies may come across as abrupt, despite the info your providing being correct, I think you should consider how you word them, as I suspect this may be what has upset the OP, who came here for advice and has received unnecessary responses. The lady who lost her gold card has been accused of fraud by some. I'm pretty sure making such accusations are illegal to make without grounds to, or evidence to support.
These things can make this forum very unwelcoming to a newbie.
The Op did indeed come here for advice. Unfortunately, despite being given accurate and constructive advice, they did not like it and things became exasperated from that point.
As Yorkie has said, if anyone feels that posts have made unfair accusations, they should be reported to the moderators. I would certianly report any post that directly accused someone of fraud, but to the best of my knowledge I haven't seen any that said that. (I haven't read every single post ine very thread).
