I had an older gentlemen approach me after getting a haircut. I was letting the car warm up, and smoking outside of it. He kept telling me that something was wrong with my motor because the exhaust sounds like it is about to explode. I tried to explain the reason for the exhaust note, and he kept comparing it to his 65 mustang. Ultimately he kept looking at me like I was an idiot and telling me I should take my car to a mechanic.
