The Guy: "Umm, I just checked your air filter, and well, it looks like it is full of dog hair."
The Guy - with a look of amazement on his face: "Umm, ya. I have never seen dog hair in the air filter before."
Me - trying to act surprised and not laugh: "Really!?!"
The Guy: "Your air filter really needs to be replaced."
Normally, I always think that the service people are just trying to up-sell me with their inflated prices on car parts, but I saw the air filter. It didn't just have a couple of dog hairs in it. It was completely stuffed full of fur. You know how when you get new towels and you put them in the dryer for the first time and the dryer filter is completely full of lint? That is how my air filter was, only worse. It was disgusting and funny at the same time. I bought a new air filter.
