My grandmother went to the Grasslake store and was using the restroom, because the door was open. She locked it. A few minutes later a lady unlocked the door with a key, scaring her and causing her complete embarrassment. She complained to the cashier and later called the manager. They are saying it is their policy to give a key to someone using the restroom. There is no notification anywhere, that a key is required. The door was not locked--it was open. The cashier didn't apologize for the upset that was caused to my grandmother and the other person. User's recommendation: Ask the management to put a sign on the door, to knock first before using the key.
