Development of "Daylight Robbery" storyline

As I tried to finalize my story I kept coming back to an idea I had last year. This story was inspired by the 6 years I spent working in the bank (where I would often visualise making a short about the various characters and their unusual behaviours- both customers and co-workers!)

 The main reason I didn't initially go with this storyline was due to the many characters that would need to be animated and the need for dialogue. However I felt these issues could be minimised by using claymation stop-motion animation.
