One thing that pisses me off about Royal Mail is their attempted delivery crap, try tomorrow!! Numerous times I've had to ride to the main office to collect. It's not so bad that it's fairly close [5-10 bike ride]but still an inconvinience.
One thing which angered me so was that the only thing they didn't leave me an attempted delivery thing for was the MD player I ordered many moons ago. They leave the most expensive thing I ordered from Amazon on my doorstep, where anyone could've nabbed it, but quibble over £30?
