It's unfortunate that the 'last mile/steps' service experience dampens the overall convenience of food deliveries. There are probably behavioural as well as economic reasons for this. The fact that other clients accept this behaviour and fail to complain has led them to modify the norm. The demand for food deliveries has increased significantly to the point that deliverers need to be more productive and avoid 'time-wasting' activities to get all their deliveries done in the time that they have to maximise their earnings.
