Was the item too big to fit in the letterbox?  Was it registered or require a signature?

Posties are not required to deliver items that will not fit in the letterbox.....they should be sent with the parcel contractor.

And they are not supposed to get off their bikes unless the item requires a signature.

And just for good measure. postmen are no better paid than the parcel contractors/couriers who get $1.35 to deliver your parcel.

I am glad his "just deserts" amused you.
