No. It only make the costumer hornier.Really specific question: At the Connudatus St. stall in the mornings, does seducing customers to keep them at your stall increase any Sexual-type Fame? Not accepting the lewd requests, I only mean the "reeling them back" actions.
The "hornyness" of the costumer is a kind of timeout you are fighting against.
The hornier they are the less they are inclined to buy anything.
Every sale you make gives you one point in business fame. (The number of flowers or the money does not matter)
