The marketing campaign for the relaunch of Nestlé's Yorkie bar ran into more problems at the weekend, when a woman handing out free samples of the bar to male shoppers at Bristol's Broadmead shopping centre was attacked by an aggrieved middle-aged man. The advertising campaign, which plays on the masculine identity of the brand and insists "it's not for girls", has already been banned from Birmingham and Liverpool after city council members complained about its sexist nature.
