Manages lunch with people bringing and not bringing it at office

Well, this solves a very personal (or whatever word that you use for a requirement by a selected few) need for a system. We eat together at work, so we need to make sure we have the enough number of lunch packets for lunch. Now we calculate manually. One person calls or walks over to everyone and asks, "you have lunch?" and does a small arithmatic to determine if we need packets from outsite

Nope, we eat one packet at a time, all people at once. So number of required packets is way less than the number present. So we can manage people not bringing lunch and still eat a decent meal. Yeah. Its cool for bachelors.

I'm going to ping everyone at lunchtime and get that update for food and do that calculation for packets online and tell someone who is supposed to go shopping. :D
