Poor old Rafa. He can't help himself. I once had a colleague who was amazingly rude and blunt with those who worked beneath him (naturally, he's now in the House of Lords). Eventually his wife had a word, telling him he'd really got to be more tactful. So then he took to saying, 'If you don't mind my saying so...' and then he'd be just as blunt and rude as he ever was before. Rafa seems to be like that. Montse will probably send him off on his first day, saying 'Now don't forget: be nice to Ronaldo,' and Rafa will return at tea time, surprised that Ronaldo has handed in a transfer request.
So Macca, was he obnoxious to the staff? Not privvy to these anecdotes.
