In terms of the post it is impossible to be efficient and not be accurate, given that a wrongly delivered item of mail is likely to make its way back into the system.
Remember I'm chasing accuracy.
The tiffin men get it right first time.
Unlike the Royal Mail who have to depend upon honest, patient and immortal citizens such as myself to assist it by making sure that their mistakenly delivered mail is put back into their system.
The problems don't only occur at the delivery end.
The week before last our inaccurate postman delivered a small package with my name and address on it immediately creating a feeling of, 'I've seen this package somewhere before'.
I had!
The day before I had taken it to my local Post Office and paid £2+ to have it delivered to an address, clearly written on the package, in Manchester. I might as well had brought it back with me.
To avoid confusion I had also written in large bold capital letters, To: next to the addressee's name and From next to my own address. The postmaster had only gone and put the self adhesive stamp/label thingy next to my address even though he knows me and my entire family by name as well as our address. The post office was not busy. I was the only customer wanting to use an inaccurate postal system.
