A Patron Falls

During the summer, there was a very sweet elderly couple that visited our library on a regular basis. Their health had been on the decline, but they still managed to make it in. One Saturday when only two of us were working, the elderly lady's knees gave out and she fell. She was very coherent and not in any pain. She said that she had a problem with her knees buckling and it happened quite frequently. I asked her if she wanted me to call an ambulance for her but she refused. I asked her about calling the ambulance several times but she repeatedly begged me not to, as did her husband. The elderly man said that there was no way that he could help his wife get to her feet but she would have to do this herself and she usually used a chair at home when this happened. We did bring her a chair and with repeated attempts and some assistance, she was able to lift herself up to sit in the chair. She rested there for about 10 or 15 minutes and was then able to meet her husband at the door where he was waiting with their car. After about 10 minutes, we called the patron's house to make sure she was doing ok and she said that she was fine and just needed to rest her legs. After this, I called our Director to let her know what happened and on Monday, the Director called again to check on her and all was well. I'm not sure if I did the right thing, though. Maybe I should have called for help anyway.
