"disgusted with services"

After visiting our G P my wfe ,with very severe head pain, she gave my wife a letter for emergency we arrived at A&E at 13.00, we waited 1hour in triage, then we were taken into majors, where we waited another 2 hours, then we were taken to EAU where my wife was told to lie on the bed, she then had swabs taken, had blood pressure taken, and an ECG, which took a long time as it was a trainee who did it,we were then told a doctor would be along shortly to examing her, 4 hours latter still no doctor, (3hours earlier she was told she was next to be seen I asked 4 different staff members for some pain relief for my wife, again with no result, I then asked a surgeon who I caught in the corridor if he could prescribe something for my wife, which he did) but still no doctor my wife then told them she was disgusted with their service and attitude and was going home, a nurse then said she needed to sign a release form, and went and found a doctor who miraculously appeared to sign her out, why and how is this possible when we had waited all this time, but the doctor still would not assess her and organize a scan, which she was sent to A&E for, and said your next to be seen, when asked how long she said about half an hour, which we were told a lot earlier
