You board the train to York. The carriage you are in is one of the type where there are lots of compartments but no corridor connecting them together. This means you are stuck in a compartment with a scruffily dressed man who looks to be drunk. He starts talking to you in a broad Lancashire accent. He tells you all about how he had a great piss-up over the New Year with a load of the lads from the building site on which he works. The building site is evidently located in Burnley. He tells you that on arrival in York he is going to get on another train back to Burnley.

He asks you whether you would like to come with him.
What do you answer?
Yes or No?
