Why would an RPI be taking details for someone travelling at the wrong time on an Off Peak ticket? Hmm!
Because the RPI initially wanted them to pay a penalty fare, which the passenger refused to do.
So the RPI moved on to trying to take the passenger's details.
Other passengers got involved to correct the RPI, who realised their error and hastily left.
This was all taking place in the row of seats immediately behind me.
Then I'm sorry, but I'm failing to understand the point you're making. You are blaming GN for having restrictions that they (and other TOCs) can't understand, yet at the same time you are saying that the restriction isn't complex.
It can't be both.
I am not blaming anyone, just commenting on the situation.
To restate -
GN have restrictions on their tickets.
You consider these restrictions are simple.
I have no comment on their complexity or simplicity, but I would expect those who have to deal with them in the course of their duties have had sufficient training to be able to do so correctly.
From traveling on their trains, I have seen at first hand this is not the case, and some GN RPIs have difficulty with these restrictions.
I do not know why GN staff have difficulty dealing with GN restrictions.
My observation was if GN staff have problems dealing with GN restrictions (for whatever reason), I am not surprised another train company also has difficulties (for whatever reason).
Clear?
