They had the salad bar going at the time. Imagine the salad bar being the centerpiece in a room and a row of people on either side of the salad bar. On one side are the Wendy's employees armed with salad materials for refilling the station. On the other side are the customers building the salad on their plates. It's almost like clockwork and an art the way they build their salad plate. The customers lined the bottoms of the plate with big, large, strong iceburg lettuce leaves to increase the diameter of their plate.

They anchored that with lots of heavy macaroni salad and other things to weight down the lettuce leaves to provide a sturdy foundation, and then they continued to pile on the salad till they had a very large platter of salad, much bigger than the original plastic plate was designed to hold. They were really piling on a lot of the macaroni salad and the workers from the other side were refilling it as quick as they could. They must have only allowed one pass to the salad bar for them to do this.
