Yes she claimed she discharged herself so she wouldn’t miss her flight and in doing so she missed the results of the tests they did. I’m sure you are correct that she was scared they were going to find alcohol and/or drugs in her system. So she said she needs to go to a UK hospital to get another X-ray etc, but she didn’t want to go today and would tomorrow. It can’t be serious then. And I agree, they wouldn’t let her fly if she wasn’t fit enough to do so.They possibly advised her not to fly tbh, they needed to do more tests but she discharged herself incase they discovered the drugs in her system. In Britain you usually have to sign a disclaimer that you refused treatment. Not sure if same there.
