As someone who gets paid to sit on hold for clients, I have developed a few techniques. The first is to get a portable phone with a headset. The second is to save laundry folding until I am on hold. The third is to find a website with neat articles that can be read in 60 to 90 seconds.
My favorite example of a single level bubble sort is organizing a deck of cards. One at a time, a card is compared with its neighbor until all are in order. A much faster method is to first separate the cards into suits and then order them. This is a two level bubble sort.
A college job was to organize purchase orders and invoices for a department that never organized anything. I first sorted by year, then month and finally by day. A three level bubble sort with alpha and beta decision tree cutting.
Two level bubble sort: Two people move the cases in four directions while the rest of the workers stack them on the correct pallets. Very efficient. Perhaps even the most efficient way to physically sort anything.

Professional bread making is done by weight, not size. Indeed, it is traditionally sold that way as well. Not a good lawsuit. On the other hand, there is a large chain that has a corporate policy to short beer pints by 2 oz. Any class action lawyers want in on the suit?
