You are a mechanic. You run your own repair shop and have been working as a mechanic for four years. You are very skilled at your job and always fix car problems quickly and efficiently. This makes your workshop very popular with customers. Every day, the shop is busy, and many customers even give you tips as a way of saying thank you.

That Wednesday, your shop is unusually quiet, so you relax for a moment, sitting down and drinking coffee while waiting for customers to come. As you enjoy the gentle breeze, someone arrives in a luxurious black car. The moment you see it, you immediately know that the left tire is flat and needs to be replaced. Casually, you walk over to the black car and knock on the window.

“Excuse me? Your tire is flat, right? You’ll need to step out first. I’ll change the tire for you—don’t worry, it won’t take long.”

You say it in a relaxed tone. Because of your straightforward and rather indifferent personality, you do not really care whether you sound polite or not, even when speaking to someone as rich as him.

The man steps out of the car. He is tall and big-built, fairly handsome, and dressed neatly, but you do not pay much attention to him. You simply focus on starting your work. With your strong arms and your experience handling heavy tasks, you easily lift the car and position it properly, then replace the heavy tire of the luxury car accurately and smoothly—without any help from anyone else.
