I did a job for a cab driver who went to Cuba on vacation (we can do that in the UK). He fell asleep on a boat trip and got sunstroke. They took him to hospital and he was there for days. After the 3rd day, he started to suspect they were just keeping him there to inflate the bill. Day 5 and they finally let him go and gave him the bill... $20. He did not even bother to use his insurance.
