Still depends on the shop.
Many years ago, when I was young and more innocent (and as now female, which unfortunately may be relevant), I took my new-to-me car to a dealership to have it inspected.
They told me (after a brief attempt to claim that they couldn’t fix a cracked turn signal lens, solved by my asking them in a loud voice pitched to carry to everyone in the waiting and sales room whether they seriously expected me to buy a new car because they were no longer providing turn signal lenses for a two year old model – lo and behold, it suddenly turned out that they had one) that the car had passed inspection, but I was about to need new brake pads, they were almost worn out.
I said ‘that’s funny, I just had the brake pads replaced a couple of months ago.’
They said ‘maybe they put them in the wrong way around, places unfamiliar with the car sometimes do that.’ (The car was a SAAB; this was about 1975 in the USA, and that was an unusual make here at the time.)
I said, ‘that’s funny, I had them replaced downstate where my parents live, at one of the oldest SAAB dealerships in the country.’
I took the car to a local mechanic, and asked him to look at the brake pads. The brake pads were fine.
So – yeah. Didn’t vote in the poll, because it depends on the shop. If my regular shop notices something that causes them to run a test and they report a problem I didn’t know about, I’m going to believe them, because I’ve got other reason to trust them. If it were a random oil change place where I didn’t know the people, I’d say ‘thanks for telling me’ – and I’d take it to my regular mechanic and have them check it; and I wouldn’t be surprised in the least if they said the car was fine.
My regular mechanic also does my oil changes, though; partly because I don’t want to put up with that crap.
