I think that's part of the "design". Everything is supposed to be easy and half-digested.  The mayo and thin wimpy vegetables are there to provide moisture - so you don't really have to "work" to chew the food.  The "chicken" is mashed, pulverized, reconstituted, and coated to fall apart in your mouth. The toppings are cut thin to do just the same.  Ketchup on fries is the same deal - it makes like two jaw-mashes turn everything into a paste so you can gorge more.  I never understood why fast food always made me feel like crap - until I started cooking for myself and appreciating the textures & natural flavors in food. Fast food is designed to let you eat enormous calorie-amounts without your stomach being volumetrically full. Then you realize you're thirsty because that fast food glop is devoid of water - and you're over-full when the water expands it.  Then I started cooking on my own - balancing flavor, letting your stomach do the processing, and suddenly I never wanted to eat fast food again.  I gotta hand it to Chick-fil-A - they do well with 'real' food. I travel like 15-20 weeks per year so I'm stuck quite often. Grilled chicken sandwich (yes, an actual chicken breast that resembles an animal) on wheat. And a salad instead of fries, with an unsweetened iced tea.  Not a bad option
