It has come to my attention....oil evac units????

I have had about 12 new vehicles and quite a few of them came with a couple "free" oil changes and or inspections. I have seen it all. Came out to my brand new truck and found fresh oil on the center of the steering wheel !!! I had a grease monkey get in my brand new car right out of the oil pit grab the inside door handle covered with grease and then proceeded to grind his greasy boots into the grey carpeting (up and over the weather tech floor mat ,a real effort to do) I took a truck in for a "Free" inspection they decided to do a the Emissions inspection without asking, got real shitty when I declined to pay for it (I lived in an area that didn't require Emissions inspections) they were pissed they couldn't screw me. I no longer put up with the stupidity , I'll do it myself and know it's done right.
