Am gobsmacked by how many people (including 2 intelligent, educated members of my team of professionals at work) think that if you are symptomatic but getting negative LFTs then you don't need a PCR. I now know 4 people recently with negative LFTs then tested positive after I made them go and get a PCR. No real point to this whinge but just scary how many people are walking about spreading covid and complete ignorance about their responsibilities.
