Greetings! Too bad to have that experience with the food, I think the cold fries could be forgiven, but definitely not the raw chicken, besides being unpleasant because of the blood it gives a lot to say about the place.
A while ago I ate with family at a place where they sell rotisserie chicken and it was in that condition, there weren't even many people and it still came raw. For me it took away my hunger :(
