Many, many threads on here about inconsiderate cinema behaviour, but I'm sure most of us just clench up and do nothing about it for fear of reprisals. It's pretty obvious who the dobber is, when you get up and walk back in and a staff member comes in a few moments later to investigate.
Howabout a prominent text number sign in each theatre that you could text with brief details, then staff could come in and the perpetrator would be none the wiser?
for example:
"UP, Screen 17, old grumpy man sitting in middle-leftwith copious balloons obscuring the screen".
"The Social Network, screen 3, on the left near the front, teenagers constantly updateing FB statuses on iphone, causing distracting mobile phone glows."
"Brokeback Mountain, screen 8, unsuitable behaviour near the rear passage."
Who should I suggest this genius plan to and will it make me any money??
