But the arrival of playground huts meant that pupils making a desperate journey to the toilets in the main building had to be issued with the secret codes, which were then a secret no more.
A member of staff said: “We may not be secure any more but the auxiliary’s supply of dry pants doesn’t get used up so quickly.”
