Or, can I?
This isn't the first time I've heard of audience members dehumanizing performers. Hecklers in the audience when people are performing in a play (not an interactive play, either)...People who not only leave their phone on, but talk on it during an event...A drunk audience member grabbing an actress as she makes her way through the venue.
That actress was me.
I used to work at the Renaissance festival, too. No one took money out of my tip jar (thankfully!), but I did have a man stumble up to me and slur the question, "Are you legal?" Wow. They used to call me the Freak Magnet, because I seemed to attract the weirdos. Rarely did they decide to take advantage.
Recently, I spoke on several panels at a convention. Awesome. For the most part. At a couple of them, two separate audience members decided that they wanted in on the action. They attempted to take over the conversation, and insert their own opinions. That's all well and good, but when you don't let the people on the panels do what they were invited there to do - speak on the panel - you're being unfair to the rest of the audience, not to mention the panelists. Again...entitlement. Yes, you paid to be there, but so did everyone else. You're not special.
If a celebrity/well known entertainer (or whatever) is walking down the street, probably going somewhere, be nice! You're in no place to DEMAND they pay attention to you. They are humans, just like you. They have good days, bad days, and busy days...just like you. If they don't respond to you on Twitter, or follow you back. Or answer your message...don't have a hissy fit.
In closing, when you're at a venue to see a performance, remember...those performers are humans JUST LIKE YOU. Treat them with respect. You'll make their experience - and yours - much better.
