"Very poor Service "

My son had a problem with his knee and we spent 3 hours in ED (Blue Urgent) waiting to be seen- in small room, without windows and with other children who were coughing and vomiting. When I asked to wait in waiting area because I don’t want us to catch some viral, stuff was extremely unpolite and I was told he can catch a viral in supermarket so there is no reason not to wait with other poorly children. Although the doctor was very nice and polite, I’m very disappointed with other staff
