How many lunches have you mindlessly consumed over the copy machine? Over a stack of papers needing grades? I find that when I am at work I am usually trying to eat as quickly as possible, while getting something else done at the same time. When you have to talk to a student after class, use the restroom, and complete other tasks during your thirty minute lunch period the time left for actual eating can be very limited. The speediness of my food consumption is not improved on a day when I am trying to eat a frozen dinner that contains noodles, using a plastic spoon, while using the copy machine because my lesson plan for my next class required wifi access that is suddenly not accessible.
