for me, the rural posties (north yorks about Whitby) have been fantastic. One guy even plays with my dog in the garden, running after an alsation is pretty ballsy for a non-family member!
but, in sheffield they're atrocious. I have had many items left outside my door (including a 'signed for' £400 crankset) with no answer, items lost at the depot and lazy posties who can't be bothered to carry my parcel. I appreciate that working conditions have gotten harder and managers are a PITA but it's not on.
Final bit of my rant, my housemate worked at the royal mail place near Forgemasters. He saw workers throwing parcels against walls and floors. They even put letters in bins. Bunch of cowboys
