Not a good place to go with an emergency

My 7 year old son hit a hole in his head. We rushed him to Meta-Clinic where we were greeted by a nurse who took us to a back room to have a look. I was holding my son in my arms and was told that his injury is not deemed an emergency and that I have to come back 3 hours later on the doctors next available time. I understand that it was busy and the doctor was not available, what was not appreciated is that the nurse never even looked at the wound or asked any important questions. She didn't tell us what to look out for should he possibly have a concussion. We were sent on our way with no assistance. We then rushed to St Georges Hospital where we were greeted by the nurses and informed that they too have a very long waiting period. They at least took the time to ensure my son was alright and gave us information on what to look out for if he has a possible concussion and what to do should he show symptoms. Even though they could not help immediately they atleast took the time to help us make informed decisions. I feel that the staff at Meta-Clinic should have at least taken a minute to give us information and not just send us away in the manner they did. They could have handled the situation in a more professional manner. I have lost confidence in the staff due to them not even making an effort. The doctors are great though and assisted us even if it was 3 hours after the incident happened. Not the first place I will go to in the future again...
