McDonald's McNugget Sauce Ratio is a Mathematical Crime

Recently, I found myself sitting across from a 20-piece McNugget box, three dipping sauces, and a rising sense of injustice. Three sauces. For twenty nuggets. I'm a network engineer by trade, and even I know that doesn't add up.

For those not familiar with the sauce allocation policy at your local McDonald's, let me walk you through the numbers. Order a 6-piece, and you get one sauce. That's a nugget-to-sauce ratio of 0.167. Order a 10-piece, and you get two sauces, which gives you a ratio of 0.2. That's your peak efficiency. The sweet spot. The mathematical ideal. But order the 20-piece, because you're hungry or feeding a group or just living your best life, and you get three sauces. Three. That's a ratio of 0.15, which is actually worse than the 6-piece.

So what's happening here? The 20-piece should come with four sauces. Full stop. Four sauces gets you back to the 0.2 ratio that McDonald's themselves established as the standard with the 10-piece. Instead, they're quietly shorting their biggest nugget customers by an entire sauce packet. One sauce. Probably costs them three cents.

But wait - there's more. This isn't an accident. Somebody in a boardroom looked at a spreadsheet, noticed that 20-piece customers are already committed to the bit, and decided that sauce #4 was an unnecessary expense. These are the people ordering the largest nugget option. They are clearly enthusiastic about nuggets. They deserve the sauce.

So what can we do about this? Honestly, not much, short of asking for extra sauce at the counter (which you can and should do, and which they'll usually give you for free if you ask nicely). But the fact that you have to ask is the point. The ratio should be right by default. The 10-piece nailed it. The 6-piece is close enough. The 20-piece is a betrayal.

The bottom line is this: McDonald's built a sauce allocation model, got it right at the 10-piece, and then threw the formula out the window when it mattered most. If you're going to establish a standard, hold to it. My network equipment doesn't get to just quietly perform worse at scale and call it a day. Neither should your sauce policy.
