Related to Korean medicine clinics

It's okay to receive treatment at the Korean medicine clinic, but... is there a possibility of being taken advantage of?

There are no fixed consultation fees here, and since the person prescribing the medication does so at their own discretion, I'm worried.

Has anyone ever received treatment like acupuncture or cupping therapy? ㅠ

I want to go if I can get a lot of help with back treatment.. I'm curious.

It seems that the elderly have received a lot of help at the Korean medicine clinic, so I'm worried.
