William　Dominos Pizza has a shop around the corner from my house. They have an annoying practice of stuffing my mailbox with “Half Price!” advertising whenever cruising by. But an angle occurred to me: If I brought in TWO half-price coupons, shouldn’t the pizza be free? So I gave it a try. The guy at the counter eventually judged the request above his pay grade so called for his manager, and after I had slowly and patiently explained the loophole for the third time, he slowly shook his head and told me that’s not how it works. I am simply posting this in case our readers have a similar experience with the same or different result, in which case, please let us know.
