Thank you Dave. It's a challenging job, but overall enjoyable. It's not for the faint-hearted at times, but I hasten to add, the vast majority (99.5%) of passengers are a pleasure to work with.
We are damned if we do and damned if we don't. But most of us have broad shoulders, and managers that have common sense - although the best managers are those that have done the job, the worst are those that haven't (when it comes to dealing with complaints, anyway).
Personally, I may not go through the train charging full opens to everybody, but I also consider it remiss of me to not mention any irregularities I come across, and if I feel appropriate (and in the majority of cases I feel it is), I will charge an excess up to the cost of the type of journey that the passenger is making, along with any supplements that may be appropriate. I also make plain to the passenger what they would be liable to if a full fare was being charged.
Is this letting people off, and does it not provide enough of a deterrent? I don't know. My role is not to make a judgement on if someone is acting illegally and punish them. That is what Revenue and BTP are for, and if appropriate (and I am able to - which is not always the case) I will involve them.
However, given the reaction of passengers, I think what I do is a deterrent, and the thing to remember is that the same people travel the same lines day after day. I was told by someone with a split season ticket last week "You are the only guard that charges for this" (he should have kept his mouth shut, I charged him a full open, not an off-peak when I heard that as he obviously makes a habit of it!). Because we see the same people, and hear the same excuses from them - and it is a case of "fool me once, shame on you, fool me twice, shame on me". If I get the same person twice, they will not get excessed twice, and even if they say anything that leads me to believe that they are a repeat offender, then they will be informed that they had their warning, now they pay, do a UFN, or leave at the next station.
