Alas this is the attitude that has brought Royal Mail to its knees. Many postal services would look at Amazon and its ilk as a great opportunity for their business, that would secure their future and their jobs. Particularly given that this could make up for a decline in business elsewhere due to increased use of email traffic.

Instead too many posties see it as an inconvenience - let the Customer (who has paid for the delivery) collect the package instead.

This is why the Royal Mail is in decline.
