Most big companies think that the way to building business loyalty is through long boozy lunches, or interminable rounds of golf, but HOK knows otherwise. Once again this year it hit the jackpot when it took over the Gaiety to entertain 1,200 of its favoured clients and staff . . . and all their children. It was their third pantomime treat and it has become one of the great promotions of the year, with guests bringing children, grandchildren, nieces and nephews along. Even the boys at the top let their hair down in time to the music, not least Aidan O'Hogan who could be seen gesticulating madly to Who's in the House? Also on their feet were Gus McAmlaigh, the IPFPUT pension boss, John Bruder, who recently moved to Treasury Holdings, Joe O'Reilly of Castlethorn Construction, which is about to build Dundrum Shopping Centre and Joe O'Flaherty of Flynn & O'Flaherty, which is putting the final touches to another shopping centre in Swords.
