Someone I know on FB is a nurse, they do private support work for a child patient (under 10) with high medical needs (and also still work for NHS)
She (my FB friend) sells temple spa on the side.
Patients mum is now doing Facebook posts about how a temple spa product gives her young daughter beautiful skin (and tagging my FB friends temple spa business)
It doesn't feel right to me but I am not sure what the rules are ?
