We were called to open this Alpha hotel safe at an international hotel chain site in Manchester. The members of staff who knew the supervisor codes had left and a guest had omitted to open the safe with his code prior to checking out.
Upon arrival there was still a guest in the room where the safe was so we were taken on a tour of other rooms where they were having difficulties, during this time we took the opportunity to work out the supervisor code and coach the staff on how to change it should they wish to do so. Once the guest had left the room with the locked safe it was a simple case of putting in the master code and it opened up straight away.
