The head is deliberately larger.

A dark caption.

She was looking around, seeing no one around. Odd. She had made an appointment here just a few days ago, and this place was bustling. Then the waiting room was filled with women waiting to schedule and now here she was with no one. No customers, no staff, nothing. She turned to walk away. She grumbled to herself. This place was obviously a scam At least she hadn't made an initial deposit or anything like that.

She went to leave, but if someone was have been near the doors to the place outside they would have never seen her exit. At least not then.

Some hours later, Sam walked away from the "spa" feeling great. It seems that only her body would be making the exit from this place, and not with her head attached to it!
