You're talking about two different things here: whether the CM's were paying attention to the safe operation of the ride and whether they were paying attention to the happiness of the guests onboard. G24T suggested that attractions CM's wouldn't even notice if the attraction started behaving in a way it wasn't designed to, which is patently false. Even lowest-caliber CM's generally notice that sort of thing, and if you've got a station with half a dozen CM's in it, you're virtually guaranteed that someone will notice.
Your reply is about whether they were paying attention to the happiness of the guests onboard. That's something that lower-quality CM's are more likely to do poorly with. Especially at an attraction like Space, where the pressure to keep the station moving is incredibly intense. Do you risk creating a downtime that angers thousands of guests just to help one who is hesitant about riding again? Even a cast member who is friendly, engaged, attentive, and eager to do their job correctly will have a tough time in that sort of situation.
