Ever had a conversation with these guys about how they do their jobs? They think in the short term and quantitatively, not quantitatively. They figure if they can get 2 subpar H-IBs at the same price as a 50 year-old, it evens out in the end.
Short story, I had a great conversation with one of these guys years back who was a manager of a chain restaurant. He was explaining to me the glorious logic of shorting ingredients to save money. How, by removing one pickle from a sandwich you could save millions a year. He was wildly enthusiastic about how powerful a management tool that shorting ingredients was. Now, as I listened to this my thoughts were on the long term effects of this policy and the promotion he was angling for.
So, Joe the manager cuts one pickle, saves the company $10 million a year and gets promoted up. Kelly takes his place and wants to move up too. So, she decides to make the buns 1 ounce smaller. She saves the company mad money and gets promoted up as well. And so on and so on until a premier chain restaurant starts looking more like McDonalds quality. But, none of those guys care because by the time the shit hits the fan they're probably cashed out!
