See my other comment about it taking half an hour to issue a ticket in my nearest ticket office.So you’re happy to give the guard commission at the same time as taking work (and job security) away from the more poorly paid ticket office staff?
Add that to my (completely unrelated in terms of ticket) inability to get anyone at all to issue me a (valid from the station I was at) day ranger ticket today at major UK city stations and you can perhaps understand why people don’t get along with ticket offices like they used to.
Do ticket office staff earn the commission from tickets they issue?
