The employees are playing a game of customer safari to see who can find the strangest customers in the store. Glenn doesn’t know about it at first but recognizes that something is “off” since the store manager is gone for the day. He tries to get Sandra to rat out Garrett, but he forgets to separate them. It’s the start to a really good Prisoner’s dilemma, but that only works when the two players don’t know what the other is doing. It’s easy to collude when you’re standing beside each other.
Dina and Glenn accidentally ruined some ballots by spilling a pot of coffee. They are worried they will be accused of tampering with ballots and face jail time. If they both stay quiet, then nothing will likely happen to either of them. There’s an incentive to confess and try to get the other in trouble, but they both know who would responsible. Since they do not trust each other, they try to set each other up by pretending to be each other and recording their voices. This serves as a credible threat in the case that one of them rats the other out.
