I booked CX. Yes I have excemption, but with what we do, we have to have our 2 cell phones on 24-7 for constant track and trace and we get confined if we have been anywhere near anyone who has become positive and we get put into 14 day quarantine. I already had two sessions of this, one of which was in HKG which was more like a Butlins camp without the entertainment. Thanks everyone for the tips.
