A boy and a girl walk into a bank carrying a large, suspicious cylinder of something. They walk poised with purpose through a corridor of offices, then passed a line-up of bored, waiting customers. The customers stop and stare. The bank tellers become distracted. Transactions, paused.
A lonely security guard takes note of their presence. He pulls out his note-pad, scrawls something down excitedly. He is anxious, nervous, but more than anything, thrilled. This will be the first time this month his note-pad will see some action.
