8. Avoid diagonals
Look closely at your waiters' speed, you can actually see that they move slower diagonally! It takes 1.4 times longer to cross a tile diagonally than to cross it up, down, left, or right (but it is still faster than going through 2 tiles!). Whenever possible, within reason, try to remove diagonals from your waiters' path.
