He said that that he, "provoke them in a way that they would try to scare," and then said the result was that he "scared them." It doesn't take too much deciphering to see it wasn't a complement or a casual exchange like you describe. Scareactors will accept complements, gladly. But stare-offs (which he later described it as) legitimately pull a scareactor's attention, especially when they don't initiate it. While they are many times used as a distraction for another scare, when a guest starts it it's a lose-lose. If the scareactor breaks first, then the guest assumes they "won" (or scared the actor). But because the actor didn't start it, there's no scare actually set to distract for. If I were the scareactor, I would be mumbling "Asshole" under my mask if this happened to me.
Scaring is a job that people do because they love it. That's the only reason why they scare. They don't get paid much and the amount of abuse the typical scareactor takes on a given night damn sure isn't worth what they do get paid. Until you do it, don't assume you have any idea what the job is like. There is so much more to it than wearing a mask and yelling, "Boo." You wouldn't tell a mechanic they're doing it wrong (unless you're a mechanic also), so don't do the same to a scareactor. Doing so makes you, yes, obnoxious.
