The memetic salesman is a humanoid SCP idea that I came up with.
He's a salesman, he looks normal at first glance. But theres one thing - the offers he makes/requests he asks, they are impossible to refuse. Literally. Somehow, he has some sort of memetic effect that causes subjects to become incapable of refusing his deal. Whether he's selling you a car or asking you to open the containment chamber, it's almost impossible to refuse. This effect only works when you hear it with your own ears. If he was talking over a phone, it wouldn't work.
Should I develop this idea further, or is it already done? Or just not good?
