Ok..but it said she left (not fired) or didn't specify in articles I read. Also a forum post isn't proof. Both of your "evidence" links are a forum post and reddit post.. I don't take them with any faith.

Plus this post makes some good points

"Her first shift back from rehab was alone on the mid? Come on now. And I heard a longer clip where she was totally fine and lucid for the entire previous hour before going downhill almost instantly. Obviously we can’t rule anything out, but it just seems extraordinarily unlikely to me that even heavy alcohol consumption would take you from totally in control to giggling on frequency in less than 5 minutes.

Not trying to discredit you or say you’re wrong, but based on what I’ve heard that just doesn’t pass the Occam’s razor test, and in the absence of any facts I’d prefer to give our brothers and sisters the benefit of the doubt."
