DUBAI-The owner of a fitness centre who sparked outrage by using images of a Nazi concentration camp to advertise weight loss services says he will donate all revenue from this weekend’s classes to a good cause. Phil Parkinson, the British founder of Circuit Factory in Al Quoz, this week posted a series of promotional images on the internet, including a photograph of the Auschwitz II-Birkenau camp with the slogan: “Kiss your calories goodbye.” Within hours he had removed four of the 10 images and apologised.
