You know how salads at fast food restaurants generally cost the same amount as a normal meal that includes fries and a drink? I think I figured out why that is, other than the whole "only rich people deserve to eat healthy and be skinny" thing. If a girl gets a salad, (notice I didn't say "if a guy gets a salad," because no guys do unless their wives are glaring them down while ordering and saying "remember what the doctor said?") then she'll probably order a water with it, what with water being free and all. That way she pays as much as she would for a regular combo, and she's not messing up her diet with a soda. So it's sort of good. In a lame sort of way.
