Like the excellent custom of handing out hot towels called oshibori to customers who've just sat down to order -- there's nothing that makes you feel positive about a restaurant like cleaning your hands (and face, although it's bad manners) with a steaming hot towel.
Your napkin (if you're not using an oshibori in a case) goes on the bottom middle, followed by the flattest object (usually the bento box).
Rounded objects (fruit, drinks, oshibori and hashi cases, and rounded ice packs) are stacked above.
