What time of day is best to post food so people actually get hungry?

The useful slot is the one before the decision to eat lunch or dinner, with the dish already on the pass. Posting when the kitchen closes wakes an appetite that no longer has a table. Note the hour the first plates leave and post before that, not once the pass is already full. The dish reel goes out at midnight, and by morning the hunger has already chosen somewhere else. Menu and dish have a fixed hour, before service, written on the calendar.
