My sons girlfriend is living with us at the moment. She announced she’s going to Dubai with friends (not with my son) she has to have 2 tests going to Dubai, none to come back to Uk and you don’t have to isolate. I want her to have a test before she comes back to our house and another test 5 days later, as I want my parents to be able to come round for Christmas. She thinks I am being unreasonable as she will have to pay £170 for each test. Am I being unreasonable?
