Here's something a bit unorthodox. I worked for 7 years in the grocery industry, and still shop at the same store I worked at years ago. At Wegmans at least, in the Northeast US, always pick the longest line. The one with the most customers. Why? Visible long lines are bad for business. Front-end (checkout) managers hate long lines. As soon as they see them, they start bringing in more people to start running more registers, and then pull people from the back of the longest lines to these newly-opened registers. This doesn't work so well if there aren't any long lines to begin with, but during the weekends and holidays, I always pick the longest line, and I always get moved to a line-less checkout lane. Never fails.
