It is understandable , most fast food joints like KFC and Mcdonalds and even Pizza outlets are meant for emergencies when you don't want to cook, want to eat something different to what you eat daily and not for frequent use..
As it is McDonalds is amidst controversies. A few years ago there was case on McDonalds branch Delhi. Then the food was declared as not healthy by the health hazards. I personally prefer a wayside Andhra meal and other eatables than for McDonalds.
Fast foods are not good for health. These companies may add harmful ingredients in access to increase the taste and sell their product in more quantity.
