I pessimistically agree with everything you say.
Furthermore.... I’d bet the two clerks will be fired for failing to cooperate with the robber and for leaving their post and abandoning the store.
You make a good point. It wouldn't surprise me. We've seen it before.
That clerk that locked him in, deserves a medal. She was cool, and calm, and probably saved her life, and the life of that woman with the baby. I wouldn't want to go back to work there though. It's not worth the lousy wages to put my life in danger again.
