Customer: “I’d like to get this DVD for my son.” *hands me a copy of Watchmen*

Me: “How old is your son, ma’am?”

Customer: “Five.”

Me: “Sorry, this film isn’t suitable for your son.”

Customer: “But it’s about superheroes! How can a film about superheroes be unsuitable for kids?”

Me: “There is a scene where one of the heroes cuts a man’s head in half with a meat cleaver.”

Customer: “What, are they thick or something? How could you put that in a kid’s film?”
