If you are an entertainment performer – and you can be any sort – you have one job; to do the best you can.
If you are an audience member you also have one job – to attend carefully to the performance and applaud at the end.
That’s it. That’s what makes it work. That’s what makes the theatre, opera house, studio, or concert hall operate.
If you are the performer who doesn’t put out the best they can do – if you are entitled or lazy or too proud to play, you are not holding up your end of the bargain. You should give back the ticket price
If you are an audience member that won’t listen quietly or look at the performer or keep seated during the performance, you are not fulfilling your part in the thing. You should be shown out.
Note that I don’t mention actual abilities of the performer, or of the audience, because these can sometimes be less than optimal – it’s the intent and the effort that makes the difference.
Or to put it simply – just as there are two ends to a dirty stick, there are two ends to a fair go.
