Once, pointlessly, in the first few weeks of lockdown one. My son had recurrent bacterial tonsillitis and a raging temperature, I called the GP for a prescription (we needed them monthly at that point, his tonsils were quietly mouldering and his surgery had just been cancelled) and were told to isolate for 2 weeks because of his temperature. I was really annoyed with this as it was clearly tonsillitis and the locum GP was incredibly rude.
Thank goodness for kind neighbours picking up his prescription.
