I think those are ohmmeters, actually. I forget what they call them, but the one they used on me to show me that I need help was an ohmmeter. I declined the help; I was only there because a smokin' hot blonde woman at Balboa Park invited me. Back in the seventies.
Yeah it's sort of a, "You see that blonde, yeah she likes you too . . . okay now you're interested come see me in the morning, cause you're sure as shit going to hell cause she's easy!"
The OP implies that this is an unsurprising development. Has there been particularly strange activity on the scientology account over the past little while?
I read it that the writer was implying that Scientology in general practices strange activity, so strange activity at a particular venue is not surprising.
