Max Hospital — Taking injection administration charges in emergency

I went to the emergency ward of Max hospital, gurgaon after injuries from a fall. I was told to purchase ATT injection and syringe. After I got the injection, it was administered by an attending nurse after she was going around for a while with the tip of the loaded injection exposed.
After that I was told to pay Rs150/- as adminstration charges. The patient has to buy injection, syringe and then pay for getting it injected in emergency situation. Is this how emergency is dealt with. I have been to many other hospitals during certain emergency situations but they first treat the patient and then tell them to replace the medication used. They never charge for administering injections.
The purpose of emergency is defeated if the patient is charged like this.
