Global line length is no different than average line length of multiple lines.

  It is when the number of lines (cashiers) changes.

  On a global average that is probably true. On an individual/personal level it is not. I take a strategic approach, there might be twice as many people in one line but it will be faster. No one in that line is breaking out the check book. They won't be arguing about a 25 cent coupon that expired. On the plus side I've noticed less places accepting checks. Personally I think they should be banned for basic consumer shopping entirely. Unless it is 4 digits, use a card or cash. As for self checkout lines there should be a huge sign that asks "are you prepared for this technology?, Really? Are you sure?"
