Absolutely 100%. A few years ago, I bought a bass on BC that I then realised had a bowed neck after I tried to (unsuccessfully) lower the action to my liking. The seller not only refused to take it back but completely denied there was anything wrong with it because they'd just had it set up. Which either makes his luthier inexperienced/incompetent or the seller an out-and-out liar. It's only when things go wrong that you find out people's true character.
My luthier managed to straighten it with heating and clamping, but I then couldn't stand the sight of it so sold it on eBay. Obviously, detailing the problem and remedial action. Lost a lot of money on it and made me very wary of buying basses here.
So huge kudos to @reggieboomboom, you're one of the good ones.
