As I said, I don't add salt to my own food. I'm talking about any time that I eat at a restaurant or get carry-out. Restaurants LOAD up their food with salt.

For example, take a look at a "healthy" option like Subway. My usual order was a 12" chicken breast sub on wheat bread, no cheese, lettuce, tomato, green peppers, and a little honey mustard dressing. Sounds reasonably healthy, right? Well this configuration contains 2370 mg sodium (99% of DV). There's absolutely no reason a single sub sandwich should be this salty. I stopped eating at Subway because I always ended up feeling extremely thirsty and bloated for hours.

And sit-down restaurants are often worse. Many don't publish their nutrition facts, but I can gauge how much sodium is in a meal just by the taste and how it makes me feel, i.e. I feel slightly poisoned after slamming down a disgusting amount of sodium.

Maybe adding a tiny amount of salt to home cooking improves the flavor. But I'm not concerned enough with the taste of my cooking to worry about adding salt. I already get more than enough salt in my diet from the variety of pre-packaged foods I eat (bread, cereal, butter, pretzels, tuna, etc.) I just don't see a need to add more salt on top of that.
