1. Does passing a roll over a plate that already has two rolls count as passing over 1 or 2 rolls?
1a. If consecutive plates have 1, 1, & 2 rolls respectively, can a roll be picked up from the first plate and moved beyond the plate with 2 rolls?
2. Does the waiter have to set the roll down on the next plate following the plate with the second roll, or can he keep moving with the roll, provided he does not pass over a third roll? In other words, if you pass over two rolls and the next plate is empty, does the waiter have to set the roll down on the empty plate, or can he move it to a plate that's not empty?
