Shops who offer autism friendly hours are welcoming to those who can’t help making noise as are cinemas.
Sessions that are specifically for those who cannot tolerate noise, are welcoming to endless noise (whether or not it can be helped)?! Really?
How would one find this out in the first place really, without purposely ignoring the stated aim of such sessions, to just see if they will ignore their aims. And than make a complaint no doubt, given how this all comes across, if they will NOT ignore their stated aims to include all 
Also, autism friendly hours, are different to the specified quiet times, which are 'autism friendly' but more..aimed towards those who have issues with noise than Autistic people who make a lot of noise. Our local cinema does a few different special sessions. Where its made clear one is for those who need quieter times, and some where noise is welcome, some where its fine for kids to actually run about when watching, sessions where babies in arms are welcome, so expect crying and such, and so on. I would be quiet pissed off, rightly IMO, if I paid for the quiet time, and someone made loud noises continually throughout it. I would not expect to go to the noisier sessions and then whinge that it was too loud for my daughter. As I am aware that the noiser sessions are to benefit other people who have different issues than my daughter. How it comes across on here, is that I should indeed be going (or at least, reserve the right to go, should I chose to as everywhere should bend to what my family needs)to the louder sessions and then complaining that they do not benefit my daughter and thus are discriminating?!
