I once had to undergo a minor operation. During the initial consultation with my doctor, he had taken notes on a patient card. This was in the first branch of the medical centre, branch A. However, the operation was to be conducted in the second branch, branch B, which included a theatre space.
On the day of the operation, the card that contained his notes had been left in branch A and hence we had to wait for the notes to be scanned and sent. But branch A was experiencing a power blackout, so branch B had to have the patient card sent via the administrator's mobile phone, WhatsApp to be specific. And the only reason I knew of the unfolding situation was that I bitterly complained that my operation began an hour later.
