Mine Host's mobile phone rings. This number is a state secret, thus the call is likely quite important.
The caller is some cute salesgirl for some life insurance company connected to American Express.
The cute voiced girl blunders onward with the sales pitch.
She misses the verbal clue from Mine Host that he is prepared to listen, but is not happy.
She drones on, Mine Host tunes out. Eventually she gets to the part where Mine Host has to verbally agree to his American Express card being debited.
He says "No".
Mine Host calculates that she has taken up Seven minutes of his time.
He informs her that he is going to divert the next several thousand dollars that customers wish to put onto their American Express card.
Waste Seven minutes of Mine Host's time, have several thousand dollars diverted to Visa or Mastercard.
Something for American Express to think about.
