When preparation times exist for a meal period, then note that a delivery/pickup time will not be shown in the ordering app if the current time plus the preparation time exceeds that delivery/pickup time. For example, assume the preparation time for dinner is 15 minutes, and the available delivery times are as follows:
5:00 - 5:20
5:20 - 5:40
5:40 - 6:00
If the order is placed at 4:47 PM, then the 5:00 - 5:20 delivery time is not available because 4:47 + 15 minutes prep time = 5:02.
Also note that if the preparation time for the meal period exceeds the last pickup/delivery time available for the meal period, then an order cannot be placed for the meal period.
