Why so many small pieces

Very unhappy with KFC gelvandale, it's not even listed here in hellopeter. I bought a 15 piece know we a bounce of people , I looked in the bag and thought they gave nice big pieces then come home and take out the 3 big pieces to see 6 wings , I meen why would I want to buy so many wings, there is hardly anything to eat, and that's not the first mess up. The and the other pieces was small excepts for the 3 big pieces on top hiding all the small pieces. Last time we bought from them we bought a 15 piece and when we got home it was a nine piece, we had to drive all the way back to get it sorted out. This is unexcepteble. You really can't enjoy KFC anymore.
