Drunk & doped? Attention seeker?
Sounds like the cabin crew handled her well.
Whether she was boarded depends on the local staff and they may have decided just to get rid of her and not have mentioned anything to the crew. Not saying that happened but possible.
Nowt as queer as fowk!
I was warned about a group of young men who appeared to be the worse for alcohol (no prizes for guessing nationality) and went into the lounge to have a chat. They had been drinking but were agreeable and accepted my ban on further alcohol service so I authorised boarding. If they'd so much as looked at me the wrong way they would have been denied boarding but they were OK.
My duty was to get pax from A to B. I would, of course, have looked a prat if they'd kicked off in flight but they didn't.
