Picking up the child at six thirty, the time from then until nine in the evening is normal dinner time for people. The early morning orders don't suit her, and she worries about her son being home alone and unsafe, so she only dares to deliver orders between six thirty and nine.
Compared to afternoon tea orders, there are considerably more orders in the evening, but they are mixed with all sorts of people and places. Not all of the communities have elevators, and those with stairs are orders that few compete for; as long as the delivery fee is reasonable, she goes for them. It's unsafe to leave the child downstairs, so she carries him up together. It's truly tiring, but having the child in her sight is much better than feeling anxious when he's out of view.
