Ten minutes later, Mai Mingle found the fourth rule.
This rule wasn't easy to find; but discovering it didn't require any brilliant deduction, just a bit of careful observation.
The fourth rule was hidden deep on the last page of the menu, at the very bottom beneath a long list of drinks. Written in a fine, faint, nearly-the-same-color font the size of an ant was the phrase, "Please do not touch the faces of dining guests."
If Mai Mingle hadn't practically pressed the tip of her nose to the menu, scrutinizing it inch by inch, she might have actually missed it.
The line below the rule provided a definition of a face: "A guest's face includes the forehead with two eyebrows, one whole nose, the left and right eyes, the left and right cheeks, and the area from the philtrum to the chin."
The seven pieces of a face she was looking for were parts of the diners that couldn't be touched... It fit together quite well.
