Answer:
Man: "So, my car broke down yesterday and I had to have it towed. Can you fix it?"
Mechanic: "Well, sure. Do you know why it broke down? That makes my job easier, knowing exactly what to fix."
Man: "No, not really. Maybe a problem with the engine?"
Mechanic: "I don't need guesses. Guesses don't help. I'll just find the problem and fix it. Your car should be ready in a few hours."
Man: "Um, OK, thanks. I'll come back tomorrow."
Mechanic: "Hey, how are you even getting home without your car?"
Man: "Oh, I'm just riding in my wife's car for now."
Mechanic: "Oh, OK, great. OH! The problem comes from the turbo air intake!"
Man: "Um, great! Bye."
Mechanic: "Huh? Oh, bye."
