Anyone in this state should have been washed before flight and bandaged! She must have been attracting flies! Disgusting behaviour and it should not have been accepted. As far as the groundstaff are concerned, they just want to be shot of the problem as quickly as possible, so all they care about is doing that the easiest way, which is pass them along the system (to the crew!).
I will never forget being met by the groundstaff at JNB who asked the Captain 'a transit passenger coming from Harare was drunk and punched a stewardess in flight. He's settled down now. You'd be willing to take him to LHR, wouldn't you?'. Err..... no, amidst hysterical laughter. You cannot expect the groundstaff to do the right thing- the easiest way to disentangle themselves is to pass the parcel straight to you! I would always go by the recommendation of the senior CC.
