Only if its part of the diagnostic and repair process, not because “hey! we saw you were coming up on an oil change so we changed it for you.” Thats illegal (at least in Ohio).

I took my riding mower in to a shop for a belt. They also changed the blades. Guess who got free blades?..lol (I had already used the mower not realizing they replaced the blades I didnt ask for).

Your situation is not universal. Yea, Gov jobs aren’t bad but not all of them are great. I was a 9-1-1 Dispatcher. The pay was good, the benefits and union were terrible. I have another gov job now and it’s great with great bene’s but you never hear from our Local. Pay could be a smidge better.
