Hospital wait times

Genuinely curious, arrived at Rockyview at 11:50 am and their sign stated a 2.5 hour wait time. I went through triage, had vitals and labs taken, and an IV port inserted within that time. Since then, I’ve been waiting to see a doctor and it is now 8:20 pm. Only a handful of patients have been called back and the nurses keep remarking on how quiet it is. The waiting room is full and they’ve had to ask family members to leave to open up seats for patients two times. I understand how triage works but how is this even possible? Or okay?

Full respect for our healthcare workers as I get it is shit right now. I just don’t understand how this waiting game works…
