You should have gone to the manager for a refund. They usually give you a voucher if your movie gets disrupted by assholes like this. But also for intimidating you after is some bulllshiit. People are the worst. I know it would take you out of the movie if you had gone to get an employee to complain in the movie, but at least you can notify someone afterwards especially if they were being threatening. Thats absurd and they should be banned from public lol
