I’d outlaw sauce bottles which make getting it all out harder, especially the ones which don’t have the opening at the bottom and make it impossible to put the bottle with the opening facing downwards.
Postman must knock and wait 5 minutes for you to answer the door by law. If you have proof that they didn’t knock or wait the required time they must redeliver the parcel by way of barbershop quartet at a time that is convenient for you.
I’d much rather ban home delivery for most parcel (stuff like couches and fridges excluded) and have them put in one of those package vaults.
The postman drives all the packages to the vault, chucks them in, you pick them up when you’ve got time (they work 24/7), everyone wins.
Postmen tend to be extremely overworked and underpaid. Many are paid per parcel delived and your idea would probably kill the job of delivery all together. Unless you plan to increase the postmen workforce by 700% and also reintroduce slavery I see no way why anyone would do that.
Yes, paying them a living wage was assumed.
