Imagine living in a country where you have to pay a shitload of money to see an American or British artist, only to have it spoilt by similar behaviour to what you have described, as well as morons who have been drinking all afternoon, and can barely stand or focus once the artist comes on anyway. And don't get me started on chainsmoking at concerts. In 2002 my wife and I drove 700 kilometers to see Roger Waters ( a lifelong dream) only to have my asthmatic wife almost stop breathing from the thick layer of smoke. They had "forgot" to put the aircon on in the venue.

Oy!
