"delay delay dealy"

I had an appointment in ophthalmology for 10.30 a.m.. (This had involved leaving home soon after nine o'clock, and organising a carer to come and be with my husband, who has dementia. They knew this, in the hospital.) At almost midday I asked how much longer it would be, as I knew our carer could not stay, I had only booked her for three hours.) I was told 'not long now'. At 12 .15 I had to leave, nothing done. Then an hour's drive home, and found carer polite but frantic, husband anxious and distressed. Now they have phoned me and say I shall have to be seen 'in theatre' (WHY? What's gone wrong?) and must travel to Carlisle again before that for a 'pre-assessment'. Two more long expensive days, and why in theatre? I did ask on the phone, but the woman telephoning was quite brusque and unhelpful.
