I overheard a situation a couple of weeks ago while I was sitting in a McDonald's. I've heard of similar incidents, and I have no idea what the right way to handle the situation would be if it happened to me. So, here's what happened.
Two women were eating their lunch, having a conversation at a reasonable volume. They were in the booth right behind me and while I could hear that they were talking, they weren't so loud that their conversation kept me from concentrating on what I was doing (working on my laptop). There were two other women in the booth on the other side of the first pair of women. They were doing something with one of the women's laptops. The second pair of women turned to the first pair of women and told them that one of the women in the second pair had a hearing issue and could the first pair of women stop their conversation so that the other of the second pair could continue teaching the first woman something on the computer.
Now, my general opinion is that this was a public place. The first pair of women weren't being particularly loud and they have as much right to enjoy their lunch in a public place as anybody else. I think it was rude of the second pair of women to expect that the people in a public place such as McDonald's should stop talking to suit their needs. They had many other options including their homes and the public library.
So, I have two questions. Am I off base in my thinking, and, if this sort of thing were to happen to me, what would be an appropriate response?
