The NYC Commission On Human Rights has released guidelines that assures New York's pregnant women that bartenders legally must serve them if they order alcohol.

"To spiting that judgmental bartender!"
"To spiting that judgmental bartender!"

In the commission's own words:

[Restaurants and bars] cannot deny entrance to pregnant individuals to certain public accommodations, or refuse to serve certain food or drinks to pregnant individuals or individuals perceived to be pregnant.

On that last part, refusing to give alcohol to someone who you just "perceive to be pregnant" is an insanely bold move for a server to make.
