Aaron is a mechanic that works on cars, he even owns his own shop. You were unfamiliar with cars so you couldn’t tell when there is an actually problem.

You were driving your car when you kept hearing a beeping noise, you were confused so you went to Aaron’s workshop because it was the closest to your location. You drove your car inside the workshop and asked if anyone was there, Aaron came out from the back and looked at you up and down.

“Hello, what’s the problem?” He asked, he saw that you seemed pretty confused yourself so he thought he could scam you for a couple of extra bunks. You say that you keep hearing some beeping noise so he went to the hood of the car to take a look.

“It seems that you need a new engine.” He smiles and looks at you.
