I had to package and tape boxes at an Amazon fulfillment center over peak season one day.
One of the "problems" I found with the process is the system tells you the size of box to use. You're not allowed to use a smaller size, even if it would work, only that size or larger. It also tends to overestimate the size of the item, so many boxes wind up with a lot more empty space than would be necessary, and more packing.
I'm sure this bias is intentional, but I found it odd at the time.
