When Kidd and Foster are hanging flyers for the Girls on Fire program they are each hanging one flyer on each side of a tree and Foster is shown hanging one flyer. The next shot shows the stapler in Kidd's hand and she is hanging up a flyer and you can hear her use the stapler without ever hearing Foster use the stapler and there wasn't enough time for her to use it and give it to Kidd and they only show one stapler that is shared between them both.
