I to a degree, totally agree with that. When operators are just doing it to their platformers to entertain themselves, it does put me off riding a ride sometimes as really their main attention should be to the riders.But I am completely against all rides just being pre-recorded as I think it makes a ride incredibly sterile and samey. The Runaway Mine Train lady at Alton Towers who does the Choo Choo thing is an absolute master class in entertaining the guests consistently. It's the same with an older member of staff on Twirling Toadstool and some rides on Detonator have been awesome, when the op has teased the guests.I myself much prefer operating rides like Black Buccaneer and Runaway Train at Chessington, where I'm able to make each ride different just by getting guests to sing, do little YMCA dances, Mexican Waves, things that make the ride a little bit more personal and for them.With rides like Vampire, I totally agree with the ride having some kind of Pre-records. Some of the ops do go a little OTT with their own voices.
