"Prescription only medication"

I feel most Ed admin staff are very rude and careless. Stayed overnight and discharged with medication the doctor thought was over the counter. Got to the chemist to be told it’s prescription only and that I was to go back to the hospital to have the medication prescribed. Call the doctor on duty in ED to confirm I can have the script written up to collect as the doctor treating me overnight said the medication is essential. Return to Ed just for admin staff to tell me I have a very long wait to be triaged for a script after explaining I had already spoken to the doctor in the department (there was no budging, admin gave me no other option but to sit with the 15-20 other people waiting to be triaged). I proceeded to walk out of emergency and call again just to be told my script will be written up and ready to collect in 15 minutes.
