The guy ordered a limited time only Double Smokey BLT Quarter Pounder, large fries, and large drink, and the combo meal came to $15.19 before tax. A double quarter pounder is 1/2 pound* of meat (*weight before cooking).
On my McDonald's app, a double bacon quarter pounder large meal is $11.19, so he paid $4 more for the "Smokey BLT" part.
