drive like a madman
A: Slow down, Adam. You're driving like a madman.
B: I told Nancy I'd pick her up at 9.15.
A: Relax. It's not even 9 o'clock yet. There's plenty of time.
B: I suppose so.
A: Did you have breakfast yet?
B: No, I jumped out of bed this morning and ran out the front door. I didn't have time to eat.
A: I've got an apple in my bag if you want.
B: Have you got anything else?
A: Pens, pencils and a notebook. But nothing edible, just the Apple, I'm afraid.
B: I'll pick something up at the airport.
A: Are you crazy? Food's always ten times more expensive at the airport.
