A lot of loads come in at night, this question could also be asked in reverse. It's been a long time since I worked anywhere that a load (morning, noon, evening, or night) was neglected because of laziness. If it's neglected, there's a good reason, such as the counter and no help.
Our orders are as tight as possible in order to keep spoilage down and inventory more manageable so we have to get most of it on the floor ASAP. It usually comes in the early afternoon.
