Yeah, screw that woman's 1st Amendment rights and her freedom to exercise her religious beliefs! I want my drink and my "right to drink alcohol"/not be inconvenienced is more important than her 1st Amendment protected rights to observe and faithfully follow her religion. And let's just nevermind I could get it from another FA, I demand it from her!

/sarc & disgust

I checked and nowhere in the Constitution is anything written about rights to alcohol. Nor marriage, ftm. But there is a lot about Freedom of/to Religion for anyone who cares to look. It's in the 1st Amendment to the Bill of Rights, codified and adopted into the document in 1793.
