Charlie Sheen's Live Performance in Detroit on April 2nd, 2011

How does anyone presume they could justifiably get their money refunded from a live show that they actually attended? It would be like receiving a refund on a plane ticket for a flight you took on which the plane crashed: be grateful you're alive...but in this case, just don't waste anymore time or money on Charlie Sheen. How could these people expect anything better than irritable ranting? Charlie Sheen is an actor. That's it. He is not a comedian; he is an actor. There's a big difference between the two. One can possibly have both talents, either/or, or neither. I wouldn't pay for parking to go see Charlie Sheen live...or even for the gas to get to the theater - but that's because I'm not an idiot. I didn't watch him on Piers Morgan either. My time has value, though; does Charlie Sheen's fanatics'?
However, I don't think it's right to heckle someone, and that includes booing them. How would you like it if Charlie Sheen (or Michael Richards, say) went to your office, and started booing you as you tried to pitch an idea to your boss? Or, say he came down to the precinct and hissed and made animal noises while you fingerprinted suspects? Or maybe he cracked some one-liners at you while you were giving your guess as to a patient's condition and throwing whatever random antibiotic you were promoting that day at them?
