Traffic Jam

Would you like some traffic jam with your coast?
Goodness, no. I’ve come here to trade my honey for some skyscraper curd. Is this enough?
I’m afraid we’ve had some excellent offers for our skyscraper curd recently, and it’s all run out. Can I get you some trainline jelly instead?
Yes, I suppose that trainline jelly will do.
Jolly good. Trainline jelly it is.
