A Hair Salon

John smiled as he flipped the sign to 'Open' on his new hair salon.

The chairs looked normal, but as soon as someone sat in them, a special hypno-screen would cover their heads and show images of...whatever, really. And the words 'TRUE SELF' would also occasionally flash. Eventually the person's brain would break and they would fully believe themselves to be the image they had been shown.

John stood behind the counter and awaited his first celeb customer.
