Yet, despite the cheap and easy menu, I'm often behind someone who is hell-bent on cranking every mathematical permutation between buying dollar menu items a-la-carte and purchasing a value meal. And these people are usually bad at math. Now I get that some McDonald's customers might not have unlimited funds, and they're trying to get the most bang for their buck, but there comes a limit. I know what it's like to have so little money in your checking account that the bank won't let you withdraw it. I know what it's like to then go to McDonald's to rely on the ATM swipe, knowing you'll get fed due to the checking account's overdraft protection. But I do not know what its like to stand in front of a cashier for three minutes adding up a pie, burger and soda while comparing it to a value meal. McDonald's is one of the biggest corporations in the world. Do you really think you're gonna come up with some mathematical purchasing equation they haven't already priced to your detriment?
