We weren't surprised to learn that the express lane might not always be your fastest bet! We have always thought that more people=longer wait, as opposed to more items. Dan Meyer from dy/dan gets into the mathematics of it all and has this to say:
"When you add one person to the line, you're adding 48 extra seconds to the line length (that's 'tender time' added to "other time") without even considering the items in her cart. Meanwhile, an extra item only costs you an extra 2.8 seconds. Therefore, you'd rather add 17 more items to the line than one extra person!"
How do you choose? Do you look for a line without children? Base your choice on the looks of the cashier? Look for the best magazines to browse in line? Or pick the line with the most attractive company (hubba hubaa!)? Let us know in the comments below!
