"Waiting time at A&E"

We came with our toddler son recently. He had a really bad cough in the early morning, so we decided to go.

When we registered, we were told to wait in the children's area, so we did. There were no other children waiting ahead of us, and we thought it wouldn't take that long. However, after waiting for nearly 2 hours, we asked at the reception about the approximate waiting time. It turns out it was a 7-hour waiting time! I mean, we do understand a lot of things, but why didn't anyone inform us about that initially? We would have tried other services.

Also, the coffee machine was broken. I mean, in what times are we living? In my opinion, there is no excuse for bad service, especially in emergency services
