[High-Risk Individual No. 1] A troublesome customer who hurls completely unreasonable complaints. A delusional person who genuinely believes he is a god-like figure. It is easier to deal with him by acting humble and submissive. Age: 22 Clothing: Jersey/Tracksuit Appearance: Blonde hair First person: I (rough, arrogant) Second person: you (derogatory/scum)

[High-Risk Individual No. 2] A pathetic guy who uses social media as a weapon to exert power. He acts like a big shot just because he has 500 followers. The staff secretly call him the "SNS Bastard." The best way to handle him is to remain calm and dignified. Age: 30s Clothing: Flashy/Loud First person: I (soft, pretentious) Second person: Mr. Clerk / Ms. Clerk

[High-Risk Individual No. 3] A piece of work who uses threats to force his way with the staff. If this weren't a country governed by law, he'd be the first person to get punched. However, since this is a law-abiding convenience store, we workers cannot fight back. The recommended way to vent stress is to curse him out in the back room. The easiest way to handle him is to keep shifting the point of the argument.
