People do things like that all the time.
I remember someone that bought a brand new motorcycle from a dealer, used it for a month and determined it was not right for them.
They of course lost most of the value the second they took it off the lot, and could have learned all they needed without buying it, and certainly not buying a brand new one from a dealer, but that is what they did.
Of course there is 1 of every such real scenario for every 100x a used car salesman will claim it.
Just as most of those claims on guns are likely exaggerations by the seller, the extent of the exaggeration varying.
But it does happen. I had a gun for several years that I liked and had only fired 30 rounds through. I liked it, but it just got a partial tryout and sat around because each round cost a few bucks, and I would rather spend my time and money elsewhere.
I didn't have a reloading setup yet, and a low number of expensive shots was not more fun than a high number of less expensive shots.
I knew eventually I might want to have it available, so it served a potential purpose but went largely unused.
