Chief executive Ivan Menezes was lured by one private shareholder into enthusing about the commercial prospects for the Johnnie Walker maker from the upcoming Ryder Cup, given that the company owns Gleneagles hotel. The private shareholder ventured innocently whether the famous hotel might provide "anything for shareholders - a cup of tea and a biscuit?" Later Humer provoked further unwitting shareholder glee when, explaining Diageo's moves to crack down on illegal tampering with Scotch whisky, he said the company had investigated ways of having caps that once illicitly removed from bottles "could not be put back on again".
