My point being that if a PAX (passenger) does't appear in a fit state to fly i.e. without causing announce, or worse to other passenger or crew or far worse, the potential safety of an aircraft, they should not get on the plane..
It's not fair or safe to the pax, crew, the industry for the handling agents/staff to try to "off load" your problem pax onto the aircraft to 'ship the problem down route'.
Thats my view as a Skipper who has had to deal with this
