I went in for a simple smog check that takes no more than 5 minutes. It was busy so I didn't mind that it took longer than usual. My problem was that I went to see why my smog check was taking so long and saw that my hood was up. Now the only reason the hood should be up during a smog check is to get a small piece of information located under the hood and then the hood should be closed. Well they took the liberty to snoop around looking for issues and took my engine dust protector off. I already do not trust mechanics at shops and this was unacceptable. I did not ask for anything more than a smog check. Who knows what would have happened if I didn't call them out on their bs. A $10 smog check could have turned into a $200 issue. Honestly pay the extra $10 dollars at a smog station to avoid any unnecessary tampering. Oh and I went to my mechanic, that I actually trust, and he found nothing wrong even though the guys at this shop told me I had a leak. Bunch of crooks.
