I got a letter in the postbox from An Post saying they had tried and failed to deliver (a relatively small package) which I found to be a particularly insulting lie as I had been inside the house painting with the front door open all day.
On the day they claimed they attempted delivery, a small chimp could have gotten the package to me. Then the next day instead of trying to deliver it 'again', they send me a small letter telling me to pick it up myself from their depot which caused no end of hassle for me.
