While leaving the place, it suddenly dawned on me that the girl might need to use it to take bus home and would panicked to find her pass missing.
The easiest way is to contact the school and get the staff to inform the parents. If the girl has a mobile phone, the parents can contact her to come and collect it at the security counter in case she is still around the area.
I walked back to the security guard and saw him handing the pass to his colleague.
I told him can just call the school directly.
He told me they have to send it down to the office as it's the procedure.
Will they just leave it in the office and hope the kid comes collect it?
