Madame Svea wanted this guy to realize she did not joke and she wanted him to get her some money which she disguised as a loan but which she knew she was never paying back. And to make sure the guy gave her the money, she used her stinky socks to scare him and to make him give it to her. She did not want to use teasing to do it.
Madame Svea was bored and she wanted to do something to take away her boredom. But she also knew that she wanted something that was worth her time. And that is how she settled on money slavery as she knew it would keep her busy but at the same time she would make some good money out of it. So she did not look back as she indulged in it.
