I know! Appalling.
Yes, the lady did make a tactical error by pointing her cane like that at the younger woman, but... why did that younger woman come up so close to her like that while she was apparently minding her own business? Was she an employee trying to help the older woman? Was she harassing the older woman for some reason? Not sure what was going on there to trigger such an attack.
Still... I can't believe no one helped that poor woman who was pretty violently thrown to the floor.
She was not an employee. She was not wearing a staples shirt.
