a lot of the restaurants i work with dont really have the staff to update the orders so i set auto timers but people sometimes actually stay in the tracking page and then call the restaurant when it says the order is out for delivery but its been a while and they havent recieved the food.
i then get a call from the owner asking if can disable this and just tell someone the order would take 45-1hr if busy in the email.
There are rules in the setting ,if more thanks x order in confirm, add x minutes automatically.
