The MPAA ratings are also just a 'suggestion'. Movie theaters decide for themselves what their policy is for admitting people into various rated movies. I know that if I don't go to the big, Regal Cinema 1/2 a mile away from me and go downtown to either of the two local places, they won't check my ID for any film.
Well, Regal won't either most of the time, but that's not my point
