My son, who will be 12 at the beginning of October, wants to go to the cinema with a friend without me. I'm happy to allow this if I drop off and pick him up (I have 3 younger children). My son suggested Incredibles 2, but his friend who is already 12 has seen it and his mum has suggested Antman and the wasp which is a 12A. I am happy to let him watch it, but unsure what the checks are at the cinema and whether it is unreasonable to say yes, buy a ticket and then find they won't let him in. It's an Oden cinema. What sort of checks do they carry out? Is he likely to have any issues?
