I had actually driven for a few weeks with the paper floormat from another shop. someone grabbed that, put it on the passenger side, grabbed my sunshade, stuffed that on the passenger side, and then tracked grease onto my carpet. I had them replace my timing belt, but after a week and a half, I went back, because the engine suddenly ran rough. They said that I needed a valve lash adjustment, which would cost a couple hundred dollars more, plus they wanted to do the normal maintenance stuff like changing the spark plugs and wires, except they wanted to charge $125 for it. I replaced the wires and plugs myself in the parking lot and the manager at the Tempe store told me to have these guys replace the timing belt tensioner, because it was off a tooth. They fixed it, but ran down my battery.
