I had my oil changed. They marked off that they inflated my tires to 35 psi, vacuumed the floors, and washed the windows. When I left my tires were 28 psi, the floors were not vacuumed, and the windows were dirty. On paper it says they checked other things like the brake fluid or the differential fluid but how would I know for sure? I assume they changed my oil because of the grease left on my fender. If you don't want to vacuum, clean the windows, or check the tires, then don't. Just charge me less.
