Hospital regulations

Hospital regulations require a wheel chair for patients being discharged. However, while working as a student nurse, I found one elderly gentleman already dressed and sitting on the bed with a suitcase at his feet, who insisted he didn't need my help to leave the hospital.
After a chat about rules being rules, he reluctantly let me wheel him to the elevator.
On the way down I asked him if his wife was meeting him.
'I don't know,' he said. 'She's still upstairs in the bathroom changing out of her hospital gown.'
