Kicked out of Zara for trying to spend money

Hi, on Saturday 4 of us were buying suits as grooms men for a friends wedding. We were in Zara Sandton and were potentially about to buy 4 suits (jackets, pants), shirts, belts and shoes. We were trying on the suits and were trying to send photo to the groom in London as it his wedding. Security then told us this was not aloud. We explained this was necessary as we need to contact the groom as explained. We were then asked to leave the store. Not only did you lose a huge sale but you also lost 4 customers for life. Good work.
