I have a shiny new staff pass from work which gives me free travel on tubes, buses and trams. It’s the best thing ever, but not so much because of the money I’ll save. The reason I’m really excited by it is that every time I swipe it on an Oyster reader a little message flashes up and it says “staff”. And each time that happens I want to tip the bus driver a knowing smile, one that says: “yep, you and me pal, we’re staff“.I haven’t actually done it.
