No, no. The worst thing you can do is go out of your way to ignore and mock a cast member.
Just be sure that I am not there.
The last time I was at WDW, the DGF and I were doing Epcot which is my favorite of the bunch. She makes out a schedule and it works pretty well except, to punish her for making me go see Ellen drone on about energy--I hope the dinosaurs eat her one of these days--I take her to Captain EO. Now we both love Michael Jackson. But I adore Captain EO (as I hope the name indicates) and she, at best, tolerates it.
So we get there and there is only cast member, a lovely girl named Amber who was very friendly and professional. But we have to wait 20 minutes for Captain EO and, as so often happens in my life, I get dangerous when I get bored.
Amber kept telling the guests not to sit down for their own safety but there was a whole family that kept sitting down. Amber would walk over to them and tell them to please stand up. Once Amber walked off, the family, en masse, promptly sat down again.
After this happened 5 times, I could no longer control myself. The family was sitting down, all of them mocking Amber. Since I was concerned about my safety, I remained standing--which gave me the tactical advantage. Yes, to quote my favorite Confederate general (James Longstreet), you must always hold the high ground.
Since I was standing and the family was not, I was in prime position to pass gas in their faces. And I promptly did so. The silent blade cuts best! I allowed myself an archaic smile, much like a statue from antiquity, as I could hear the family complain about the smell but, of course, they did not realize that I had ripped one on them on purpose.
I suppose I should be ashamed of myself and there are times that I actually am. But they had crossed the line so to speak in disobeying Amber who was there representing the Mouse.
I have done many bad things in line. One time, I was on Space Mountain and this little boy is so afraid that he has to get out of line. I shook my fist and waved it at the parents. "How do you expect your son to be a man if he does not ride Space Mountain?" I demanded.
The family did not hear me but the woman in front of me did. She turned to me with a look of horror on her face--and then she started laughing as she realized that I was correct and trying to shape a manly society.
I did a jerky thing. But I think the family that mocked Amber were acting even more like jerks.
