Going to McDonalds and ordering a Mcdouble, a Chicken Sandwich, and a small fries. Take the chicken patty off the chicken sandwich and place it in between the patties of the Mcdouble. Put all the small fries in between the buns of the chicken sandwich and put sweet and sour sauce all over the fries sandwich(other sauces will work fine). Then eat the fries sandwich as your appetizer and the Mcdouble chicken sandwich last. This is how to get the most bang for your buck at McDonalds.
