Its a classic but still annoying

Did some work for a small client - demonstrating what we do, how we would do it and the results they would receive. I then spy this morning that they have taken all our advice and decided to try and do it themselves to avoid paying our "very reasonable" fees. Its pathetic really and i am not going to let it damage my general optimistic view of people's intentions, but i hope they really enjoy the saving of a few hundred quid by tucking us up. Anyway, lets move on....
