Businessman: You don't like flying, do you? John McClane: What gives you that idea? Businessman: You wanna know the secret to surviving air travel? After you get where you're going, take off your shoes and your socks then walk around on the rug bare foot and make fists with your toes. John McClane: Fists with your toes? Businessman: I know, I know, it sounds crazy. Trust me, I've been doing it for nine years. Yes sir, better than a shower and a hot cup of coffee. John McClane: Okay… It's okay, I'm a cop. Trust me, I've been doing this for eleven years.
When McClane reaches up to the overhead compartment, his gun shows. He responds to the concern on the gentleman's face.
