My car is squealing when I come to stop at a stoplight. I need to have the car looked at.
Okay, could you describe your problem in more detail?
I don't know.  I think it might be the brakes.
Okay, so is it a problem with your brakes?
Yes, I think so.
Okay, do you have a preferred auto mechanic?
No.
Okay, here are a few highly rated mechanics: Mechanic A 1 mile away on Street Alpha, Mechanic B 2 miles away on Street Beta, Mechanic C 3 miles away on Street Gamma.
