Doctors, at one time, were there to be seen when you felt the need to see them. Now they are there for you when it suits them.
If you were to worry that your 'sniffles' were turning into something worse, then told to wait a day or two for an appointment and wake to discover that a ten minute walk, pleasant enough in the sunshine, has now to be done in torrential rain...the son-in-law promise to try and pick you up turns to nothing as traffic snarls up in such weather, for much the same reason the bus service suffers.
Might all the doctors have been busy with patients and nursey happy to get her last appointment out of the way before lunch?
Might there be a GP's mini-van service in operation to ensure that the infirm but willing patient get to their appointment?
Was the jab perhaps to counter the effects of melancholia?

Ignorance is bliss, bliss is happiness, I am happy...to draw your attention to the possible connectivity in the foregoing.
