I guess it makes sense if the place is huge/hectic and you want to "industrialize" the serving of food while reducing mistakes (wrong table, wrong order, kitchen mixed orders, etc). It sounds "cool" when you say that the transitions between states can be handled by anyone on staff with this type of system but it would also feel impersonal if you have 4 different people handling each state: take order, pay, bring food, ask feedback.
