My doctors just come out and call your name and walk you to their room themselves. I have yet to ever see a nurse, technician, assistant, etc- even with the two recent trips to A&E, the doctors themselves did everything- came out and got you, vitals, everything. I actually find the whole experience much more personable, like they really care about you, even if it is really, really slow to get anything done, like a simple ultrasound!
I'm sure you'll be just fine julia-mel. Report back and let us know how you do ;-)
