“Hi, return to the railway station, please.”
“That’s £2.90”….

….

“Hey Missus!  Missus! Missus! At the back of the bus!”
“Wha? Me? Sorry?”
“You’ve got to get off the bus!”
“Sorry?”
“You’ve got to get off the bus. I forgot I don’t go to the railway station.”
“Oh.”
“Yeah, I only go this far and then head back. But don’t worry, I haven’t over-charged you or anything. It costs £2.90 to get this far anyway.”
“Oh, OK.”
“Have a nice day.”
“Yes, you too.”
