Have you, by any chance, noticed the increasing number of self checkout aisles at grocery stores and big box stores? Do you ever wonder why a merchant would purchase an expensive and complex machine, rather than hire another 2-4 checkout clerks? Do you ever wonder why pizza vendors use conveyorized ovens; or, why Burger King uses a conveyorized broiler? Do you wonder why there are a growing number of automated car washes?
