This midget lady accused the shop keeper of short changing her (he hadn't). So she stood on the confectionery with her dirty shoes and started yelling at him. Very threatening behavior but the shop keeper can't do anything about it because he would get arrested if he tried to throw her out of his shop physically. In the end she just destroyed some of his stock and left. She sounds like she is on drugs so maybe she does not know what she is saying or doing. London rapidly becoming one of the most violent cities in Europe.
