Sales – Manipulate Business Perk

Recently one of my Sims achieved the top of the Perception Business Perks: Manipulation. This can be activated by the Sales … Manipulate action. The sim has a gold sales badge too; I’m not sure if that affects the outcome of the action. I tried it a few times, and it was successful in making the customer buy the product, but they would immediately lose a star. It seems like they get very angry for being manipulated. So I don’t think I’ll be using the manipulation much, even though the same customers have gained the star back later. Do you think the Sales – manipulate is worth losing a star?
