It's not worth arguing over sick notes
I don't think we give sick notes simply to get patients to rate us highly ('Demands with menaces', Copperfield).
Entitled demanders are definitely going to slag off the doctor who gives them the note, whoever is unfortunate enough to see them next.
We give sick notes simply because there are some patients we are never going to educate and so our energies are best conserved for those with whom we might possibly have some level of success.
I never argue the toss over a sick note because I simply don't regard it as worth it any more.
