He is employed a as entertainments manager and yes he does act as if he owns it! He is no longer at the Cavendish, he was done for driving in a bus lane on Christmas Day in Plymouth and the article in the Herald Express said "formerly if the Cavendish". It could be that he only works for them in the summer season.
He used to own The Grosvenor, Kestor and another hotel, but not the Cavendish. He was supposed to go back to The Grosvenor as entertainments manager but he didn't. They were having lots of work done and did not open for the full season. The bloke who owns The Grand in Torquay owns it now.
