After all, getting your packages to you safe and sound is pretty much their entire job. For one Stevenage postie, however, the definition of safe has taken a little bit of a hammering.
At least, that's what Lucy Cowell thinks. She returned home to find her order from Marks & Spencer placed in the safest of safe places - directly under her doormat, complete with a friendly note telling her where she could find it.
"I couldn't believe it when I saw the photo of my doormat on top of the package," said Lucy on receipt of her package.
The Yodel delivery person, fulfilling an order from Marks and Sparks, had placed the package in the safest place that he could find to protect it from the rain.
As the doormat flopped over the sides of the package, it probably did keep the rain off, so maybe we shouldn't complain too hard.
"My husband, Richard, 57, had seen the peculiar item outside our house when he came home from work. I have experienced bad deliveries in the past but nothing like this.
"I don't understand why the doormat was on top of the box," said the mum.
"My friend had sent me a bouquet of flowers to apologise for spilling wine over my walls at a house party. We've had a few laughs over it since and I'm only sharing it now to make a few more people smile."
"On the note posted through my letterbox it stated that the parcel was under my mat," said Lucy. It certainly was under the mat, no doubt about that. "It was so funny and even looking back at the photo now makes laugh."
Yodel, the delivery service, were forthright in their defence of their employee.
"We were asked to leave the bouquet in a safe location if nobody was home and our driver left the mat on top to protect the box in case it rained.
"We didn't have any contact from Lucy about the delivery and hope that she enjoyed her flowers," they said in a statement.
"Our driver understands that the parcel could have been better camouflaged, for which we apologise, and now leaves Lucy's deliveries in a more discrete location."
