Add in your typical fat's poor ability to gauge calories along with their tendencies to underestimate how much they ate and you end up with salads just being a vessel to eat ranch and toppings off of. Honestly, I'm convinced that fast food/restaurant salads exist solely as an option to make fats that wanna pig out feel better about themselves. Never in my year of serving did I see a fat order a reasonable salad, always either covered in meat or waterboarded with dressing or both.
