Yes, but most people don't want to make 12 tacos at once, so if I just randomly decide I want tacos tonight, it's just cheaper to go to a fast food place then go to the stores and buy ingredients for a 12 taco homemade kit. I'd also have to do the math, because I think it's still pretty even. I don't buy cheap hamburger when it's on sale or whatever it was you said so $5 for hamburger meat plus the cheese, lettuce, sour cream, it's about $14 so divide that by 12 and it's roughly the same cost or more than fast food. Then there's the actually having to make the food. Which you don't have to at a fast food restaurant.
You motherfuckers making me hungry for homemade tacos.
