Scientific Precision Down to the Millimeter

"The beef inside a McDonald's hamburger is forty-five grams, placed on an iron plate X millimeters thick, with the surface temperature maintained at Y degrees, and grilled for Z minutes. This is also determined according to scientific research. As for X, Y, Z, they are trade secrets; I regret that I cannot disclose them."

"Do you know how thick the bread is in a McDonald's burger? The answer is seventeen millimeters. Scientific research has proven that bread is most flavorful when chewed in the mouth at a thickness of seventeen millimeters. Additionally, the optimal size for the air pockets in the bread is five millimeters; hence, the air pockets in every McDonald's bun are exactly five millimeters. Regarding the thickness of the bread, extensive scientific research methods are used, regardless of the cost, to reach conclusions."

"I always insist that everything at McDonald's burger restaurants must be based on scientific principles, that is, operations must be scientific and rational. For example, the Coca-Cola sold along with the burgers is most delicious at a temperature of four degrees Celsius, so the temperature of every Coca-Cola refrigerator around the world is set at four degrees, which shows that the management of temperature is not negligent. There was a time when I went to a "Qiezai noodles" shop to eat and asked the owner what is the most delicious temperature for noodle soup? The owner shook their head and couldn't answer. I believe that if traditional food were to adopt scientific management, it would definitely pose a serious threat to my business. Of course, "Qiezai noodles" with more than thirteen hundred years of history and widespread popularity, if developed using scientific methods, would certainly see a rise in sales."
