Standard letter for people who think their time has been wasted:

We are sorry to hear that your hour spent with us was a waste of time. Having spoken with the Time Lords, we are happy to inform you that your hour has been refunded. For administrational reasons, the hour has been inserted into your life beginning at 2:34 am on April 9th, 1998.

We hope you were awake and able to take advantage of the extra time.

Yours sincerely,

THE MANAGEMENT
