I am not saying what class or where or when or who

But once I went to an exercise class and they were doing exercises where you try to stand still in a position

An old woman complained that an old man laughed at her because she was moving around instead of standing still

She tried to complain to the instructor that it was disrespectful that the other man laughed at her and get into an argument

Now the instructor usually would make jokes that are politically incorrect so people would laugh
