"Minor injuries unit"

I took 4 hrs off work to try and attend the minor injuries unit before it shut at 5pm. Arrived at 4.25 hours to be greeted by a sign stating that no more patients could be seen today. If you shut at 5pm you should update your website to state that you must arrive before 4pm if you want to be seen. I assumed that as I arrived well before 5pm I would be able to wait to be seen. There only seemed to be about 3 people in the waiting room. Now still in pain and have to explain to my boss tomorrow why they gave me 4 hours off work and I still have not had my injury looked at. Not very impressed!
