Last time I went the cinema issued two tickets for the same seat ( SW The last Jedi on opening night), and the cinema was full.
I was sat in the seat and this guy comes up and says I'm in his seat. I explain I wasn't. We checked both tickets and had to go see the manager. He had no clue what to do.
So I said it's simple isn't it. Who bought their ticket first (I knew I bought it the day it was released). I went and sat down. Not sure where they squeezed him in.
2 years before that (same cinema), I bought a ticket for SW on opening night (and one for Mrs AFB). The one screen was almost full but there were two other screens showing it.
Anyway we went and sat in the theatre, no one else was there yet.
5 minutes before the film was due to start a lady came in and checked our tickets again (still no one else there).
She explained they had originally planned to show it on three screens, but were now only showing it on two. I was about to kick off but she took one look at my wife who looked like she was about to break down at the thought of trying to find seats in what would now be a full cinema, and said she could play it in there but it would just be the two of us.
Result! I was more than happy. No people talking, no noisy eating, no smelly people!
