regular inspection of my car

Today, I brought my car to a dealership to get the regular check up. They have shuttle service, so they drove me my office in the morning and picked me up after work. It is convenient service for customers. Anyway, they replaced engine oil and filter. Those were free because of ECP(extended care protection?). And they also checked air filter, lubricate locks,latched and hinges, lights, horn, wiper, coolant, brake, washer fluid levels, adjust tire pressure. I can check these things though. Then they found out that my pollen filter was so dirty. They charged $52.90 for replacement. And I asked them to clean up the rear seat. When my daughter ate snacks in the rear seat, it got lots of chocolate or some snack stains. They chaged for $20.00 to do it. When I got on my car, rear seat was not perfect, but I could say OK. However I found that "SOMEONE SPILLED COFFEE IN MY CAR!!!" I could wipe off, but please be careful.
