In reply to Star1973:
Our wall is in a leisure centre. It is not always staffed, only at busy periods. There is a written test to do to sign up (admittedly it is not brilliant, but receptionists with no climbing knowledge can pass or fail people, so it serves it's purpose).
If there were no staff at all, you would very soon get bored as routes wouldn't change.
I think the suggestion of proposing the business case for opening it, as suggested above, might be best.
Our wall runs with a full time manager, and a small team of freelancers.
