That’s, “If you know, you know.”
Specifically, in this case, when your mechanic tells you: “Your car’s inspection is all set! No issues.” Entering the weekend on that news is always great! (I wasn’t necessarily expecting issues, because everything’s been running fine, but I’ve had this vehicle for almost two years without needing any significant work done to this point, so I’m at the point where I start getting antsy every year at inspection time.)
But yeah: If you’re a New Yorker, you know the relief of “Inspection’s done, no issues!”
