I also find it quite funny the amount of pages dedicated to those who find being asked to show a railcard is some affront to humanity or an example of making life difficult.
Many years ago, when I used to sell plane tickets, we asked for the passport of the intended ticket holder. A single person could come up and buy tickets for as many people as they wished, as long as they had each and every pasengers ID so we would put the exact name on the booking. If the buyer didn't have that we couldn't sell it because if we were issuing the ticket the name had to match the passport precisely. If we went on the buyers word and there was a mistake, well, we would then be liable as we would have sold a ticket not knowing if it matched the passengers ID. If someone went online and bought the ticket and made a mistake then that's on them. I suppose I'll be told my customer service was atrocious, I deserved abuse for this and I wasn't doing my job, going by the logic of some on here?
On that note it is quite ridiculous to suggests that customer facing staff who get abuse are somehow bad at their job and they need to change thier attitude. I've worked with people who I consider and I consider myself to be someone who Remains calm and professional when dealing with irate customers. That doesn't exempt me from abuse, if a customer is going to be abusive they will be abusive to whoever is telling them what they don't want to hear. It makes no odds if that employee is the epitome of customer service or not.
The customer is not always right and I find those who trot that line out just expect employees to break rules on a whim or constantly make exceptions for any and every scenario, rendering the rules pointless and ignoring the fact they may get in trouble from thier employers.
