Hmm
Oncology- I'm still to find a female onc consultant who doesn't wear nice flowy dresses and big glasses and hugs everyone she sees lol
Ortho: Mainly male, very tall..macho...rather posh
Anaesthetists: Not met one I've not got on with yet, and I'm working with them in a few weeks for 3 months too- so very excited, I guess some can be a bit sarcastic, very laid back!
Optha: All very odd...and have an odd sense of humour lol On clinic one doctor had a dr who lunchbox with a lunch his wife had made lol
I can't think of any group of doctors I've come across other than those and they all have similar characteristics. However It's the same in nursing, and I reckon its because when you work with people so much you start to copy sayings, quirks, attitudes etc
