Lynne and 'Mantha are out. Lynne sees the local snooker champion on crutches and points him out to 'Mantha. 'Mantha is shocked and asks Lynne how he broke his leg. Lynne tells her that he tripped over on a number 147 bus. 'Mantha says that it sounds painful. Lynne agrees and adds that it was the 147 break he didn't want.
Wimbledon has a local snooker champion. Lynne does not tell us which snooker championship he won but it was likely to be the Wimbledon Open. If he was a professional, he probably wouldn't be getting the bus.
'Mantha doesn't read the local newspaper so doesn't know about the snooker champion's accident. She prefers to ask Lynne about any news because it gives them something to talk about. Without that conversation starter, they would most likely be sitting in silence.
The snooker champion was on the 147 bus when he broke his leg. We don't know exactly why he was in the Wanstead/Plaistow area. He might have been going to watch West Ham United. He has decided not to sue Transport For London as the unwanted attention might affect his training. Lynne looks very angry at the end. She had a large bet on him winning the South West London Championship.
