Two meats in a hamburger!

Few weeks ago, I went to Macdonald to eat hamburgers with my family. I bought two hamburgers and fried potatoes of S size. My brother bought three hamburgers and fried potatoes of M size. When he ate a hamburger, two meats were in a hamburger!My brother was very pleased. At that time, Macdonald tried to serve hamburgers in sixty seconds. If they could not serve them in sixty seconds, consumer could get free hamburgers. I think  that it is difficult to serve hamburgers in sixty seconds. Also, The project was big burden for shop assistants.
