Did a whole heap of businesses rally together and petition govt?  

No, Bob.........this is strictly political...........just like all the efforts in state legislatures to either ban abortions altogether, or to make it extremely difficult for any woman to obtain one.

Seriously???????

I've seen signs in businesses that say something along the lines of:

This business reserves the right to deny service to blah blah blah - but I haven't seen one that says 'happy' people are banned.

The local RSL is one.

Outback pubs had signs-no shirt ..no shoes..no service.

Most of the signs went when blokes entered with --shirt ..boots and nothing else.............Richo..

A YL-entered one of those pubs with a sign out side.

--everyone knew she was a tourist--had a.. map of tassie with her....................Richo.
