I bet they were white and rich.
I reckon the following is not far off the mark with first four dominating betting:-
1/33 White and Rich and Voiciferous
11/8 Non White and Rich and Voiciferous
1/2 Medical Staff and Rich but claiming to be poor
1/1 Nursing Staff also claiming to be poor and probably the only staff members to tell the full truth.
3/1 Hospital Porter (males), poor too, but never failing to speak up when there is a microphone near.
6/1 Hospital Management Non Patient Facing saying nothing
10/1 Support Staff and it doesn't matter what they say.
33/1 Clerical Staff below the least management grade. Who know enough to remain silent.
If the Enquiry that was called for goes ahead, I'm looking forward to the results. It shouldn't take more than 10 minutes, but I bet it drags on until late autumn by which the 65+ should have received the first dose of the vaccine.
