Because she knew all the saleswomen in this store didn't know her, she didn't directly show her identity to them, but chose to threaten Jing Yunyao.
Yu Yin smiled with mockery. "Great, do it now."
Mrs. Tong really wasn't a smart woman, because a smart person wouldn't destroy his or her own business for a so-called friend.
Coincidentally, Yu Yin knew the owner of this store too, and she knew its boss wasn't dumb. It was impossible that its boss would treat them badly because of Mrs. Tong's unreasonable behavior.
Instead, if Mrs. Tong insisted on making it a serious problem, the owner of this store might cut their friendship, because Mrs. Tong simply made enemies for her.
