Well again, no. The railway has its rules and those rules state that the ticket remains the property of them at all times.
Its up to businesses to adjust their own policies to suit the mode of travel not the railway. We provide a service, we do not and really should not have to bend over backwards just because some companies either do not trust their staff when they make expenses claims or do not have a satisfactory system of travel payments within their system.
Lots of companies have these and for them its no problem - person buys tickets - gives them to staff. No problem.
Sadly its attitudes like this that show some people working on the railways don't fully understand the reality of being a customer facing industry. It's up to railway companies and their staff to adapt their systems to suit customers. Otherwise people just drive, or fly, or take a coach etc.
I am always advocating use of the railways to friends and colleagues but it only takes one bad experience with jobsworth staff to put people off rail travel where they have a choice of mode.
A small minority of rail staff take great pleasure in being unpleasant to customers and enforcing inflexible industry rules (real or imagined), its a shame as 99% of staff I meet are really nice and go out of their way to be helpful.
As I say I have to retain tickets for retrospective travel claims, I don't have access to a company credit card and we don't have a corporate travel agent. I make 4-6 rail journeys a month totalling £100 or so. If I get a barrier assistant who insists on keeping a £30 ticket that money comes straight out of my pocket.
Alternatively I can pick up car keys at my office reception desk and take a pool vehicle straight to my destination, guaranteed no cost to me. If I need to stop for fuel, no problem, the petrol stations are happy to give me a receipt with all the details I need, no danger of not getting paid the costs.
Now I stick to the train despite this as I either buy long or stand my ground with barrier staff / find a nicer staff member but I can see why colleagues just don't bother using trains after those sort of experiences.
