I went to watch the Irishman at a cinema near circular quay last year. A Lebanese family, maybe about 12 people including 3-4 year old toddlers brought in in prams (this is a 18+ film), some adults and I guess a grandmother stormed in to take their seats about 10 minutes after the movie had begun. Throughout the movie children were making noise, crying. 40 year old guy in the group stood up about 30 mins in and took a phone call started speaking and walked out. Whole group got up several times for toilet/ food etc. 2 hours in they got bored and all walked out never to return (4 hour long movie).

I really don't know what causes this behaviour. A lot of them are actually wealthy as well. Very strange.
