There have been episodes where we heard Shula, Lynda & Pat (?& Oliver) all thanking Rob for doing something they thought was very nice of him. I don't listen every day so I probably missed some of Knob's other enchanted fans. But Roy said "Not everybody's cup of tea", so folk must acknowledge that Knob is marmite. Roy can't exactly take a moral high ground.
Whatever happened with Kirsty & Roy thinking the other had sent V-cards, btw?
(hahaha, just thinking Kate Aldridge could be the perfect counter-foil to Knob, she's too woo & self-centred to be easily charmed!!)
When Knob argues with Adam in cricket or with Tom over the business, Knob gives the impression it's because he cares so much about the game/business, so it seems more forgiveable.
I am currently betting matters will end with Knob going to prison. Maybe for a crime against H&H.
