What are the laws on drinking whilst pregnant in your country?

I was just wondering what country your from and what the law on drinking alcahol whilst pregnant is there?

I was talking to a friend who works at the pub and got into a convo about when she first got her RSA (responsible services of alcohol)

She was telling me about a pregnant lady that came in everyday and stayed hours drinking vodka, she went to management and asked what the rules with pregnant women and drinking in bars/clubs/pubs was and was told that pregnant women are not to be discriminated against and are to be treated as everybody else...served whatever they order until they become agressive or abusive then they are cut off. ..This is in Australia.
