Leta -- I had several first-trimester scares, including bleeding and loss of fluid.
And, thank God, I moved from my small one-doctor clinic to the clinic of a big hospital, Baptist.
While Baptist has its faults, its nursing staff were GREAT every time I had a problem. I could call at any time and get good advice. When there was any chance of a problem, they "squeezed me in" at the last minute -- they did this on three occasions. And once, when I had an episode at an odd time, a staff member called me at home and told me to go to the hospital's 24-hour outpatient clinic.
The nurses remember me personally every time I go in -- which is something, since they have SO many patients.
I think this is because of economies of scale. The prenatal unit has 3-4 full-time docs who are there all the time and what looks like a dozen nurses / receptionists. They can shuffle to make time and space.
As for service in HK -- it's certainly not as gracious as it is in other places. This is a place that prizes speed and efficiency above all else. But I rarely find it very rude. 90% of cabbies will go slowly over speed bumps for me if I say I'm pregnant. I don't have problems at local restaurants, even cheap take-out, rice-box places.
I think it's also the customer's demenor. I speak fluent Cantonese and I'm a naturally polite / soft-spoken person, and it usually works. And I tip. Even a small tip will go a long way if you're a regular somewhere.
