Heard a discussion on Jeremy Vine yesterday, whereby a postman had gone to the cinema loaded with his own snacks ... not bought at the cinema.
His bag was searched and told that he could not take them in.. asked for his money back.
His opposite guest was a rather strident lady who stated that cinemas were a business and you wouldn't go in a restaurant with yer own steak and ask them to cook it (not a good example methinks). Always thought cinemas were there to put bums on seats and not an add-on sweet store.
Although, I never feel the need to munch and drink whilst watching a film .. can be annoying with the crinkley wrappers, etc.
In some cases, the confectioneries cost more than the tickets.
Think they may be pushing their luck here with some punters.
