Cashier,  holding up bottle of nail polish teenage girl has just purchased: Would you like a bag for this?
Teenage girl, smiling politely: Yes, please.
Friend standing next to her (completely serious): You don’t need to waste a plastic bag for that, don’t you care about the environment?!
Teenage girl: No, I’m a Republican! *takes bag and walks away*
