I have made numerous posts in the thread, so have been following. The point is I don't accept that it is a core part of the business. Fair enough €2.38 might only buy a cornetto, but there's generally more than one person viewing a film, so this is not particularly relevant.
If you had read all of the posts you'd also realise that there isn't a consistent policy applied by all cinemas - most don't have any notices despite having them for non-smoking, mobile phone usage, prohibition on recording the film, noise etc.
Some posters have stated they have gone to certain cinemas with the food openly visible without being stopped.
The cinemas inability to run its business profitably purely from box office takings and advertising, premium seating, phone/online booking charges is not my problem - until I am explicitly told not to bring my own food and drink I will continue to do so.
