This is interesting. Here is a story from the NY Times about a Supermarket that has adopted Bank style lines for grocery store checkouts. Whole Foods is the one trying this and I would love to see it in action. For me the problem is usually that there are 15 registers but only 3 or 4 people working them.
I don’t see how this would speed up the line at all. But instead of there being 4 or 5 lines, everyone gets into one line and they are called upon with their cart similar to a Bank. I’ve waited pretty long in bank lines too, so again, the problem always comes down to how many people are manning the checkouts/tellers not how the line is formed. Am I right? What do you think?
