Yes, I know, bus crews don’t wear those badges any more.
But, as you will have gathered, I have one foot in the past and I like to dress the part when conducting on a vintage* bus. That’s why, if you’re a passenger on the Service 400 “Exmoor Explorer” when I’m rostered, you’ll see me kitted out as a 1960s bus conductor. [Edit: sadly this service no longer runs. Also, I no longer work for that operator!]
