I'm pretty sure the golf club is owned by BL, hence Martin's involvement.
And I agree Olivia, Kathy was rude to Caroline. Mind you, her life is pretty shit, Kenton telling all about the invites problems, her son being best man - I do feel the SW's have really just put too much crap on her plate. Whilst Jolene just gets everything handed to her on a plate, albeit, Kathy's plate 
Its quite funny really as most soaps make people 'pay' for their affairs but the archers. In fact you're positively rewarded. Which reminds me where has ruaridh been this whole summer holidays - I presume he's been off for 2 months and therefore at home?
