person A: I went to pick up my car from the mechanic and found a huge scratch on the side! They are saying they didn't do it! I am so mad right now!
person B: Oh my gosh. I am not surprised they denied any wrong doing. I think that is typical of mechanics. What do you plan to do about it?
person A: I guess I can't do anything but write a bad review.
person B: I think bad reviews are important though. A lot of people use those to determine where they go for service. You may save someone else the trouble you have.
