Check the whole diner scene
A strange customer is only one part of the picture. Compare five areas before acting: face, body or pose, table and objects, wider camera scene, and whether the route is obstructed.
If one detail looks unusual, slow down and compare the other areas. The public material we found does not establish a universal rule that one clue always means reject, nor does it provide spawn chances or a complete official catalog. The observation checker can help you record what you saw without pretending to know the hidden result.
