I remember eating at Burger King in a German airport about 20 years ago. I ordered some sort of crispy chicken sandwich with coarse breading. I think it was some sort of local special. The whole thing looked very similar in quality to these advertisements. The lettuce and onions and tomatoes were good and the chicken seemed almost real. The bread was like from a bakery. Haven't had a sandwich like that ever since and I think about it randomly. It seems possible to achieve the standard in their advertisements. People seem to be gradually tolerating lower quality food such that they can get away with what they actually serve today. But I’ve noticed this trend outside of fast food.
