They are currently just getting back to normal after there busy season with the RenFaire you very likely just got a lot,of salt or the extra fry bit on the bottom.
I've never had a problem with the fries n salt. But they could have changed the course of the salt. To make it grainy
No. They frequently add sand to the fries. Helps with digestion. Shop early enough and try their breakfast burritos. They add r.t.v. caulk to them for that "extra cheesy" effect.
More than likely, its just from them getting back into the the usual, probably just a little bit of extra salt.
