Edit to add, on a more serious note: If I was an NHS employee I'd be absolutely outraged at the implication that the quality of treatment they provide is dictated in any part at all by the patients' political views, rather than by the (lack of) budget, training, and available staff, which Labour is complicit in.
Seriously, the more I think about it, the more annoyed this bullshit is making me.
That's far more likely. Although hospital staff aren't supposed to prioritise celebrities, I think they have some leeway if they believe having them sitting the waiting room will cause security or other issues.
