Dear Sir I Wish To Make A Complaint

What must it feel like to be arrested and accused of a murder that you didn't commit?

When we get faulty goods or a bad service most of us like to get it off our chest by firing off a letter of complaint. There must be millions of them written every year, all destined to be a bit of extra work for somebody to deal with, and then dispatched to their "Rubbish" bin, never to be seen again.
