Regal Moraine Pointe Cinema 10

I'm a teenager, and every time I go the movies they never card me to see a rated R movie.which I see quite often. they never have. I just went to see the purge anarchy tonight and all of a sudden they can't let us in cause we are not 17. regal better understand that they lost a ton of money from not letting us go into the movie. I think it's very stupid that they can sit there and never card you but out of nowhere they have to? makes no sense. if you're gonna card please do it everyday or simply don't do it at all.
