Not too often at McD's nowadays. Usually only with Arch or when I am out and there is nothing else available.
My usual is a big mac meal with a coffee, sometimes a fillet of fish on the side, and maybe an apple pie.
When I was in my 20's my work lunch was often a big mac meal with banana milkshake, with a quarter pounder with cheese, and a fillet of fish, and an apple pie.
I still have a free coffee to collect....
I haven't been to a KFC since I heard about people finding badly healed broken bones in the chicken wings and legs. Didn't like the idea of the chickens being injured and suffering for my food.
However, many years ago I did once eat the whole a ten piece bargain bucket, with all the fries, baked beans, coleslaw, Vienetta dessert and half of the 2l bottle of cola all in one sitting, on my own, in the office, at work.
Haven't been to a Pizza Hut for a long time.
