Flat coke & no water!

We went to see a 6pm movie Sunday evening and were offered FLAT COKE (all flavour's were flat) and when we asked for water instead, there was no stock. How can you charge customers for flat soda's and not even have water available as an alternative? And on top of that - we were told we could not bring in our own drinks.<br> <br> Pathetic - totally ruined the movie experience.
