****** and dishonesty

Took my car in to this shop because my brake warning light came up. The guys had a look at the brakes and said it looks okay but the owner has to confirm. I went to the toilet while the owner had a look. Without him knowing I could hear him speaking from the toilet window. Heard him telling his employees not to tell me the customer that the part doesn't need replacing. They must just do the job which was over a R1000. When I came out and asked the employee to tell me the truth and why would the owner insist on replacing a part he pointed to my skin color. I decided to do the job never go back there again and write this review to make people aware of the level of dishonesty and ****** I experienced at the shop.
