We get settled in seats at the back of the cinema and realise that the youngest has left his glasses at home and can’t see the screen.
"It’s okay," says my wife. "We’ll move forward when it starts, there’s plenty of room."
But people are coming in all the time and I can’t live with that level of uncertainty. So I go off to get our seats moved. We’re still on the ads so there’s plenty of time. On the way out I clock the rows further forward that have spaces - ammunition if needed. But actually I’m quietly confident; the whole thing’s shaping up like something out of a customer service training video and I’m sure I’m going to win the sympathy of the Odeon staff.
