NRU74, thanks for the "Support Worker" explanation. As you say, an apparent waste of whatever resource "Support Workers" constitute. A reflection on the quality of NHS management, an unfair non-typical one off experience, or the tip of a monstrous iceberg?
OTOH, Mrs C has recently attended a couple of out-patient appointments in a nearby town for consultations concerning an eye condition. Very little sitting around, a series of tests conducted by nurses, and finally a reassuring talk with consultant. Can't think of anything to complain of other than about the damn hospital parking ticket issuing machine which would have challenged Turing, I think.
OP, nothing helpful to advise I'm afraid, as mercifully I've been spared this injury to date, other than to add my very good wishes to those of others.
