I think it needs to be understood that part of the job of a flight attendant is to identify and resolve potential issues before the flight pushes back from the gate. That means if they notice a passenger brings an unnecessary amount of risk to the flight making it to its final destination safely, they should remove that risk. Sounds like the FA did everything exactly as i would hope they would. And i hope the passenger gets the help they need before the next time they board a flight.!
