“Many people are invoicing me at the moment”

This weekend, I heard the best ever response to all those insincere, slimmed-down corporations who make you wait forever while they play bad music and tell you how important you and your call are to them. Next time they send me an invoice I am going to email them a note saying:

“Thank you for contacting me. Unfortunately, many people are invoicing me at the moment, but I will assist you as soon as I become available. Your place in line is ... seventeen. Thank you for waiting. Your invoice is very important to me.”

Think it will work?
