Message to all bands

In those days I have been hearing many musicians complaining about drunk careless ungrateful and "deaf" concert visitors who do not deserve our attention and effort. Is that really true ? What shall we do ?
I address to all the bands : please, while performing use less rude vocabulary!People come to the concert to enjoy it, to relax and have a nice time. Secondly - pay attention to your instruments and practice a lot.
I myself feel a big responsibility while playing, I want us to perform as perfectly as possible. Music is like a prayer, it's a message.So try to teach people how to understand it. People are worth it.
