> Some moments later, Worker H, the lady who was helping Cutter E and Cutter F and who was working too hard to have noticed anything about what was going on with the lines before, said, "There's four lines," and at that point the 8-10 waiting in the bank-style line sort of drifted toward the registers and ended up in grocery-style lines once again.

I was a grocery store clerk in high school, and noticed that upon the creation of a new line (or in this case three new lines), there was a mad rush to be first in the new line. To assuage this, I would try to arrive at my register incognito, and then quietly pull the second person in line from the nearest register. Occasionally I would be spotted, however, and upon arriving at my till with my chosen customer, I would find a smug soccer-mom stacking her boxes of Jalapeno Poppers on my conveyor belt. So I was surprised by the drift described.

That's all....I have nothing to add to the opinions stated by the others.
