Rather like the parcel delivery van drivers being expected to rush about like dangerous lunatics.
An area of work where H&S COULD usefully intervene, because competition is causing a lack of safety and high levels of stress.
If the customers all have to pay an extra 50p per package...so be it, if it means that YOUR family isn't in a head-on with a delivery van, or every time the parcel man knocks on your door and then leaves a card because he hasn't got time to wait for you to answer it.
