It can go the other way, of course.
I had a chance during a business trip to the US to try out a range of different basses in a number of music shops (both large and small). I happened on a s/h Ricky 4003. The set up was OK - not ideal, but fine without any need to "fix" anything before I got it home. After a thorough in-store noodle, I took the bass to the very helpful sales assistant to finalise a deal. It was already cheap by European standards. The sales assistant goes through this whole spiel about how great these instruments are, and that he's a bass player too. He plays it just to show me, just in case - being European - that I hadn't registered his words. The conversation went something like : Assistant: "Oh, that action is way too high. I'll fix that for you while you wait". Me: "It's really OK for me actually". Assistant: "Are you kidding me? It'll only take a second".
Fast forward to the big "snap" sound, when the truss rod snapped as he went at it like a gorilla!
Assistant: "I guess you'll not be taking this one after all". Me: "You got that right!
Maybe I dodged a bullet that day.
