Yeah, in my entire time of going to the cinema and sneaking snacks in a backpack, not a single member of staff asked me or other movie goers about it.
I think it’s only questioned if you openly bring in say, a bag of minstrels of a share bag of doritos.
I mean shit, the smaller hotdogs that VUE sell are like a fiver which is an absolute rip off. You’d think with popular films coming out they’d make a killing with the revenue from the tickets being sold so food prices wouldn’t be that shite.
