Essex is in the North!!!

We had a card posted through the door yesterday. The name on it wasn't us, but the first line of the address was the same as ours.
The rest of the address was for a place in Essex! Now apart from the fact that Essex is about 200 miles away, how did the people who sort the mail not notice this slight anomaly? The postman must be blind (doubt it), stupid or just plain lazy! It's no wonder the Royal Mail are losing money left right and centre.

Mind you they'll probably get sold off ASAP if their Chairman has anything to do with it. Allan Leighton was the Chief Executive of Asda who sold it to Wal * Mart and then did a runner with all his cash! Asda went downhill after that (well took a nosedive to be honest).
