The new Southmead hospital is an airport. 

There’s a shuttle bus from the car park 

(Though you can walk in five minutes.) 

You check in on arrival 

And walk through a vast atrium to the designated gate. 

There your credentials are checked and they say:

‘Oh, sorry, that clinic’s not running today. 

We shouldn’t have made that appointment. 

Can you come back tomorrow?’

I think they need better ground control.
