This could make me unpopular for expressing such an opinion, in fact a "right-on" some years ago tried to paint me as something I'm definitely not for expressing this.

The thing is - I understand some countries qualifications aren't recognised in the UK, but others are. It's already been said the origins of some medical staff in the NHS in this thread.

In personal experience, I've never met a decent doctor from one certain country. I won't name the country, or the doctors, I certainly could and am very tempted to, but...

Example one, this man was notorious in my town for being a complete ..... Rumour had it he was a failed surgeon and took his failure out on patients all his working life. He put my grandfather at risk. Well, I'll tell the story. My grandad could hardly move with pneumonia. My dad phoned the emergency line and the doctor on duty was unfortunately Dr "M". My dad described what was happening, and this M was abrupt as usual and demanded my dad bring him to the surgery. It was sleeting, my dad wrapped my grandad up and somehow got him there. M took a look at him and started shouting at my dad telling him off for bringing this man out. My dad flipped and shouted back saying it was his bloody insistance, with M saying you will not talk to me like that I am a doctor.
I know many many cases regarding this atrocious doctor.

Another Dr "U", he was known to have a racial dislike of whites, but nothing that could be proven. Plenty of stories of his abruptness and dismissal of patients concerns.

Another, Dr "G", I was warned not to go to him as everyone in Brighouse hated him. He got my medical history up, and started laughing at me because I had depression at 14-19, he made fun of the thing I was worried about.

Another at a local surgery, it was near impossible to understand him, he wore a dirty hat and the receptionists warned everyone to try avoid him.

All these have a thing in common, not just where they got their qualifications from, but that they were in the wrong profession?
