Ever had an urgent project, the client must have it done whatever the cost. You pull out all the stops and deliver it. You put in our invoice and suddenly hit the Pied Piper syndrome.

As you may recall The town of Hamelin had a rat problem; biting babies in the cradle, etc. The people were ready to lynch the mayor and guys in charge, then this geezer turns and up promises to solve the rat problem and is offered one thousand guilders – these guys are desperate. So our man Mr Piper was true to his word

“And the grumbling grew to a mighty rumbling;
And out of the houses the rats came tumbling.”

So the towns rat free and Pied goes to collect his grand, but the Mayor’s problems are over. So the mayor tells Pied to take 50 guilders and be happy with that.   Now I’m sure there’s a lesson here…
