That seems like a really piss poor attitude to have if you're operating or are responsible for the maintenance of a ride. I do hope you're not in either of those positions?Even if reported to the right person, this does not mean that action will be taken.
Most "complaints" by guests are just random, or some thoosies who feel like they know a lot about rides when they don't. And if you called maintenance 10 times for nothing, just because a guest felt like something happened, you won't do the same for the 11th guest.
A friend and myself once had another kind of "incident". Upon riding a rollercoaster, we did realize that one bearing made some scratching sounds on the lifthill. As we had a fast pass for that day, we did what every sensible thoosie would do - we rode in different rows to find the wheel in question, realizing that in additon to the sound, the wheel in question produced a jolt every rotation.
It was already clear to us that the bearing had an issue - this is not critical, as it still worked good enough, but we knew that it had to be replaced soon. So we told the ride-ops who called maintenance and told him which wheel it is, and what we experienced. It should be noted that he spoke close to no english, so it was not that easy to explain it to him.
Anyway, instead of simply taking a ride in the seat we told (and showed) him, that would have made it clear what happened, he stood on the lifthill for 2 rides to listen to the sounds (the catwalk was on the other side of the defect bearing), and then left without doing anything.
To be fair, when I was at the ame park a week later, the issue had been fixed.
Long story short: Even if they hear what you say, they might just don't act on the spot. Either to keep queues under control, or simply because they don't want to waste the time during the day.
No matter how many times people get things wrong, not matter how many false reports, no matter how many nervous people confuse something normal for a problem, all reports should be taken seriously and looked into.
That 11th time will be the time your wheel assembly falls off!!!
