Pugwash thanks - good to know that there are/should be procedures to avoid this sort of situation . I suppose it's possible that the person herself when it became obvious that she would be v late home fed up with waiting and longing to be out of the hospital and at home ,resisted attempts to get her to stay . And I suppose it's also possible that she dismissed the ambulance crew and didn't want them putting her to bed . I find it hard to think that the ambulance staff just abandonded her in her wheelchair at midnight . Well ,I hope there's more to the whole sorry event .
