Avigdor --- I feel your pain. I would only add that these actors are learning VERY bad habits early on.
If any of them are seriously thinking of professional careers, they'd better think twice about this and act professionally NOW. You can laugh all you want about "karma" but it's true in this business "what goes around, comes around."
If you screw people over, it will come back to bite you later on. You may not even be aware of it directly, but I've known of actors giving killer auditions and not getting the part... because they were branded as unreliable. They would never hear that conversation though, and they'll walk around wondering why they didn't get cast. It comes back to them, believe me.
And be careful who you brush off now, or treat unfairly. These are the same people that you will meet again and again in the future in this business. The guy next to you in the chorus who you're dissing may turn out to be a future Rob Marshall.
The theatre community and even Hollywood are actually pretty small. I'm always amazed at how connected everyone is. That "six degrees of separation" game is really being generous. In most cases, it's only like one or two degrees from everyone else.
Word gets around, and people do remember.
Start behaving like you want to be treated by others NOW.
