The story gos that there were a few complaints from offended pax. i would have found it hillarious though.
Virgin crew do like to have lots of silly fun on board, to entertain themselves as well as pax. Like dressing up, doing a service in a funny hat, teeth, glasses etc, this goes down well especially on orlandos. It doesnt happen on every flight though but there is usually a good atmosphere and sense of fun between the crew, and most of the time pax pick up on that and seem to like it. However there was a time when there were a few memos floating around about not taking advantage of virgin flair just to get away with any kind of behaviour.
