I don't blame Qatari's in the cinema...it's wrong to single out a single race. It's people in general who are ruining movies, the Dukhan cinema is the same and I think you will find few Qatari's there.

I personally blame the cinema management for allowing this to happen.
If they really gave a damn they would do the following

1)before each movie show a short "please show respect to others in the cinema" clip, highlighting expectations.

2)station ushers in the cinema to look out for and remove persistantly disruptive people.

If anything cinemas must be loosing money due to people not attending due to the behaviour found inside.
