The caps are removed from ALL bottled products, to prevent fans from launching the bottles filled with liquids to the field and hurting someone. It stems from the Kyle Turley game when the Saints were playing the Jets on a Sunday night game and Turley ripped a Jet’s player’s helmet off and threw it about 20 yards. The fans went ballistic on the holding call that was made and the subsequent helmet toss, by throwing half-filled bottles of liquid on to the field. It was insane. Some bottles did not make the field from tbe upper levels and were landing/hitting fellow Saints fans in the Plaza level. I was there; saw it, but was fortunate not to have been hit. It was pretty darn scary though, sitting in the Plaza and constantly looking up. Not pleasant.
