A double double is not the same as a big mac, a double cheeseburger is probably closer and its 2.97 in California. And probably 10 cents more to add lettuce. It is true that the dd is a bit bigger but not twice as much, and not as big as the double qpc. Mcdonalds is trash anyway.
I wonder the shipping cost of tens of thousands of McDonald’s vs the less than 400 in-n-outs?
