Well... if i worked in a bar, i would be fully conscious i would be serving poison for people, pregnant or not. I would be fully conscious people could die by driving drunk, commit crimes, and do all the shit drunk people do.

So, if my conscience would let me work in a bar, that would be cause i would not give a damn about people. In this case, i would serve anybody, pregnant or not.

Anyway, i hope never to work in such places...
