Outright discrimination

What is it with bar owners and the Human Rights Act? Two years ago there was a spate of them trying to raise the drinking age by themselves, and discriminating against 18- and 19-year-olds. Now some Wellington bars (or at least its bouncers) has decided not to admit the old. This is of course illegal - as illegal as refusing to admit people because they're Maori. While they may not be a bar's ideal demographic, older customers are equal members of society, and deserve to be treated as such.
