The Brick Part 2

An old lady gets on the train in London heading for liverpool with her little terrier (ankle biter) and sits in the non smoking section.
When they reach Crew a young man gets on board smoking a ciggarete (can't spell) and sits in the non smoking section opposite the old lady.
She kindly asks him to extinguish the ciggarete to which he replys " no, can you please shut your dog up" as the dog is yapping away at him.
The lady takes offence to this and calls for the ticket vendor, the vendor then asks him to put the ciggarete out to which he again reply's " no, can you please ask the lady to shut the dog up"
The lady then takes the ciggarete out of the mans mouth and stubs it out.
what happens next?
p.s: the final part later on
p.p.s back from blackpool
