Does your plastic surgeon's office have a private entry or do you have to go through a lobby where there are other businesses?

I had a deep plane face lift and a bilateral blepharoplasty. On my second post op day I was scheduled to go back to the office and have my drains and dressing removed. I assumed, wrongly, that there was a back entrance to the office. In order to enter the office, one must go through a lobby that services several other professional businesses. My husband went into the plastic surgeon's office to inquire while I waited in the car. To my horror, I was told I had to walk throught the lobby. Just when my husbsnd and I entered the lobby, my daughter in law and my two grandchildren, ages 8 and 10, we're coming out of the elevator. They had been to see the eye doctor who has an office in that building. I had a soiled bloody dressing on my head, drains with blood in them pinned to each side of my head, my eyes were swollen almost shut and my face and neck were swollen and very bruised. I was mortified, the children were terrified and their mother shocked. I had my head down and the scarf I had over my head had slipped off as it was windy outside. Even if they had not recognized me, they would have recognized their grandfather. This happened five days ago and the children are still upset. What should I do to try and help this situation? I told the clinic manager what had happened and she said that they do not use the back entrance. Please, if anyone has words of wisdom, I could use them right now.  ed
