In spite of constant reminders to turn off your cellphone some people continue to use their phones in the cinema.
Lani Selick was trying to watch a film recently at the Varsity Cinema, while the man sitting next to her was constantly texting.
"I leaned over and I basically said to him, 'Excuse me ... would you mind turning it off."
But he didn't.
So the fourth time he whipped out his phone she put her hand over the man's device, to block the screen light.
The man abruptly left the theatre and returned with an usher who escorted Selick out of the theatre.
"I was shocked, absolutely shocked," Selick said. "The usher informed me the police had been called."
The man alleged he had been assaulted by Selick.
Police questioned both parties but decided not to press charges.
A spokesperson for Cineplex says if you see someone texting in the theatre go and see a manager, rather than dealing with it yourself.
"When it does occur our theatre managers are very happy to deal with it," said Mike Langdon of Cineplex Odeon.
