Not right but welcome to the world. This is the same thing we have been experiencing now for several years from our clients. For decades in the past contractors without a local large presence in expat locations were part of the host company medical, triage, and emergency evacuation process. No more. We have to charge them a higher rate to inefficiently provide services for our people and in so doing can’t compete with companies who do not do the same.
If one of us got in medical trouble we would go to one of the doctors that Shell Oil had. They would be Dutch or English. As we were not Shell Oil employees we would pay cash, but we did get good care. I vividly remember an expat that had a car wreck. I picked him up and took him to them. They patched him up and took care of him no questions asked. I am sure they billed his company.
If someone was in critical condition the only answer was a medivac back to Europe. Oddly enough the UK was very good if you were a for pay patient.
When working in Nigeria a lot of workers carried medivac insurance to get us back home if we were in bad shape. If you were in bad shape and could not get medivac, you would probably die.
