ELI5: why does fast food salt taste different than table salt when it should all be the same chemical formula?

It might just be me, but I always think that McDonalds and other fast food places' salt tastes... saltier? Do they add something to it?

McDonalds buys salt that is very finely ground.  They keep it in little packets, where it can't clump and recrystallize.

Ordinary table salt is much more coarse.  This keeps it from coming out too fast, so you don't oversalt things.

If you want some super fine salt, buy "popcorn salt" at the grocery store (not the kind with artificial butter flavor).  Don't complain if you put too much on though, the folks at Morton's warned you.
