Had a show where there were two kabuki drops. It was supposed to go: cue 1) kabuki drops, revealing artist. cue 2, 30 minutes later) 2nd kabuki drops in. cue 3, a short time later, 2nd kabuki drops for another reveal.
Instead, the guy in charge set the timer for cue 2 to happen 30 seconds after cue 1, nearly dropping the 2nd kabuki on the artist.
