Totally normal at our local hospital, but they will give you an estimated wait time, usually a minimum of 5 hours, so you know to leave and come back.
Which isn't always practical.
Several years ago my DH suffered a minor stroke and spent the night on a rapid assessment stroke unit. He was discharged the following morning but was unable to leave since his prescription wasn't ready.
The prescription he was waiting for was for several days' over the counter aspirin of the strength we already had at home (300mg).
Having been diagnosed with a stroke, he was not permitted to drive and I do not drive. For one of us to return to the hospital, later that day, would have meant paying £36 for taxis both ways to collect his prescription when it was finally available. (We have no family living locally who could have collected it for him or taken me to collect it and a patchy bus service.)
Eventually, he was allowed to return home in a taxi on the basis that someone would return to the hospital later that day to collect his aspirin.
Once he was home, I refused to do this and told the hospital we would be using the aspirin we already had at home. He had been given a discharge note with dosage instructions when he left.
It would have been ridiculous for me to pay a further £36 for two more taxis, while leaving him alone at home following a stroke, to pick up over the counter tablets which we already had sitting in the cupboard or could have bought from the village pharmacy less than two minutes away.
