As far as a screaming "argument for post-natal abortion" goes, I agree, it would be affecting the ambience of the lounge - people go there to relax before their flight, having a brat yelling and screming does nothing more than annoy people.
But as far as dress codes go, I think they need to be looked at realistically.
I agree - my whole point was not that people go in there in a suit / shirt and tie ; far from it, but I've noticed some people go in there with just 'any old clothes on'. My point (re: Dajop) was not intended to disrespect Dajop or anyone else, but I did notice that the dress code wasn't being enforced that well in some lounges. As Gordon rightly pointed out, you certainly wouldn't get into an RSL with ripped jeans on, let alone footy colours.
If you're coming in to change after a hard day, good on you Dajop. It's when people just rock in, in any old clothes and show a lack of manners that it bothers me, because it just shows a lack of respect for other people. Especially rocking in with a screaming child (after all, in the T & C, it does say that QC members are responsible for the conduct of their guests (and themselves too).
I wouldn't go in there in ripped jeans and footy colours, simply out of respect for the other people. I can understand, and would make an allowance for QLD and other hot places, with respect to shorts, but for instance, I wouldn't wear them in a lounge in the Middle East, and certainly would be mindful of what my partner wore, just not to offend anyone there.
I agree on the other bit as well - which is that screaming and shouting (from anyone) does bother me more than dress, because you can block that out.
