My overweight father-in-law does this, and my husband used to but I've since taught him better. Whenever I'd cook something, my FIL would douse it in salt, then bitch to me that it was too salty and I didn't know how to cook. No fuck it's too salty, I've already salted it. But my fat bitch of a MIL can't cook worth shit and doesn't use salt because she's already had a heart attack and is probably due for another (oh please be due for another!) so I suspect that's why FIL and hubs got into the habit of just salting everything without tasting it first.
