Many moons ago I worked at a store that sold whippets to restaurants for whip cream dispensers. The Grateful Dead was in town for a 3 day concert All these dead heads in dreads, tye dyed shirts and smelling from no baths for days would come in and buy them by the box full and claim they were with so and so Bbq joint and were running specials on all their pies with homemade whip cream. Lol. Owner realized what was going on and said we needed to take off the shelf I said heck no we need to quadruple the price. We did and we still couldn't keep on shelves. They would have them out in the car leaving parking lot hooking up to some type balloon contraption and releasing from balloon and sucking it out before getting out of lot. Haha
