You were just wondering if we would have any hints on this page, weren't you?
The "eat lunch" puzzle is obligatory in a Mathcamp puzzlehunt. In earlier years, instead of an actual puzzle, this was a task teams could do in order to earn a free answer on a non-meta puzzle of their choice. But teams rarely if ever used the freebie, so I decided to change things up.
To the teams who backsolved this, I hope you still hydrated yourselves!
