This article on getting the most out of your burrito-scarfing experience at Chipotle by William Hudson at Thought Catalog was better than I thought it could be.
1/2 meat + 1/2 meat = 3/2 meat. Forgetting is natural, like Chipotle meat, so let me remind you that when you add fractions you only add the top part, when the bottom part is the same number. Therefore, when you’re asked what type of meat, and you say “half chicken and half steak”, it should equal one serving of meat. But it never does. Because a scoop of meat is kinda just a scoop of meat, and nobody in Chipotle management has yet introduced new “half” scoops with which to more precisely address this perfectly legal request. So use it. IMPORTANT: Unlike with the beans, you should make your position on the half meats clear from the beginning, otherwise they charge you for “extra meat.”
