"Please arrange chairs so people can sit by themselves"

In my GP’s waiting area there are chairs in blocks of three or four. Someone came and sat next to me and I had to get up, I can barely walk, there were seats but I didn’t feel comfortable sitting in between people, I prefer to sit by myself, anyway, the reason I had to move was because the person who came and sat next to me stank to high heaven, I felt sick, I had to go away and stand by myself, even though I can’t stand very long.  I don’t like smells. I don’t go out much because I am worried this might happen. How the doctors and nurses deal with these smells, I would love to know?  Please arrange the chairs so people can sit by themselves if they want.
