EWL:- I'm with BSB, you did nothing wrong, indeed you appear to have gone the extra mile, as usual, for your client. The day that pax are required to prove their state of mental health when buying a ticket is the day some responsibility will devolve to you (the ticket-seller). Anyone with a shred of common decency will feel for both you and the client, but her plight is more the responsibility of the State Health Authorities and, more importantly, HER FAMILY! There is far too often an attitude that failing faculties of the elderly are too much trouble for family members to supervise, a sad, sad state, and they seem to expect that the state will provide. Yeah, right!!
Chin up, mate, you did more than was legally necessary for her, now that the proverbial has hit the fan let the "authorities" use their resources to help the family rehabilitate the old dear.
Kind regards,
