"Waiting at the Emergency Department"

Want to first of all say every member of staff I came across were fantastic. 

I feel the waiting room was really stuffy making it difficult to sit in and there is no water available - a water dispenser would be great. 

I would say the majority of announcements over the tannoy you could not make out who was being called. People around me were also commenting that they couldn't understand the announcements also. Would appreciate a screen which also displays your name or a number system like used in maternity for clarity.
