"Some horrible staff"

My friend has been in the Royal for a few weeks now and I've been up to visit him nearly every day. Some of the staff are very nice but some are absolutely vile, so this suggests to me that the training is poor and inconsistent. Most of the foreign nurses are very good but I'm ashamed to say the local nurses are not. They speak to the patients with a complete lack of respect and leave them unattended for long periods with them shouting out for help saying they need the toilet only to be told really aggressively, "Shut up, I've said I'll be with you in a minute, didn't I?" I've reported it to PALS but I doubt they'll do anything. After all, Liverpool invented the Liverpool Care Pathway.
