Medical bill vs Headset

Today, I received 2 items from the delivery.
1. A bose headset ordered by Sir. *Yeah*
2. Medical bill from the recent cell extract @ thyroid/neck.
It is a procedure similar to blood withdrawing ... A syringe was poked directly at the neck and extracted the cells. *OUCH*.

Well, what is the cause of medical in Singapore?
Apparently, it is more expensive than the headset.
