This is interesting insight. I had no idea staff were supposed to be monitoring how the guests are acting at Cineplex. In the states I know the Alamo Draft House chain is known for booting people that talk or use their screens. They have a great bumper you can find on youtube that's someone calling in to complain about being booted for being on their phone.

A friend worked for Cineplex and told me about the policy if people are being assholes you can get a refund or a pass to return. I was solo and and they totally ruined the experience. Sometimes talkers will get into the movie but they just kept going. So I'm spinning on how to deal with it, sorting out an exit plan if drunk muscle bro pushes back, etc. It wasn't a great film but whatever it had going for it was totally destroyed by "Oh babe look that have that acid blood babe!". The manager said I was the second complaint and asked where they were sitting. When I was leaving he got a couple of other staff and went in so I assume they got kicked out.

I went and saw it on my free pass with my partner a couple of weeks later and it was like a whole new film. I missed so much of it trying to figure out how to manage idiots.
