I’m sorry for offending anyone, but it WAS “terribly rude”.
I appreciate the “Kovod” this woman was bestowing her ailing mother, but at whose expense? At the expense of the speaker? What about at the expense of the people sitting aroung them? Did anyone think of that?
She had absolutely no shred of a right to do this unless she received permission from the speaker first, as well as permission from the people in her srroundings.
