The next evening, I received a text message on my cell phone about a promotional 3-for-2 offer from that very Speed Rabbit Pizza outlet. I had made the mistake of giving them my cell phone number, because they wanted to call me if the pizza delivery man got stuck in a door. I have been receiving such weekly reminder messages every week for an entire year . And since they also had my home address, they could even send me promotional envelopes by mail.

I am quite protective of my personal contact information, and actively avoid doing business with any company that contacts me without my permission, so I have taken my business to Pizza Hut instead.

Total money made by Speed Rabbit pizza from me: €8.53 (without tax)

Total money spent by Speed Rabbit pizza on sending me promotional messages: 52 × €0.07 (text messages) + 5 × €0.7 (postal mail) = €7.14 (without tax)

Total money earned by Pizza Hut because Speed Rabbit sent me promotional messages: around €105 (without tax)
