What a creepy old man. In a more... horrific sense. Reminds me a bit of that Convenience Store horror game
At least it wasn't sexual harassment, but at this kind of job she really does meet all sorts of people, so it wouldn't be surprising for some other creep to have made a harassing comment at least once... yeah, that is kinda scary. Hang in there, Ri-chan.
Despite the tough look she's also a big softie, so... I suppose this stressful and potentially miserable job contributes to her actually stressed out look.
