They dont always do it, but mistakes happen. I've had mail for others in the small block of flats. So you're saying you've NEVER received mail meant for someone else? When humans do things, mistakes can be made.
That's like saying, due to the rare occasion a postman keeps mail, that all postmen do it.
Since February, we've had new doors fitted and each has a larger number plate on the door..... These are newer doors with better fire-resistance, ever since that huge block of flats that was on fire last year, most local councils, have improved fire safety in all their multi-appartment buildings.
In the 3 ish years I've lived here, I can only think of a couple bits of mail I was expecting, not turning up.
My address details are correct
