I only found out about a secret code after I just finished delivering takeout.

Every time I hand the meal to you, I’ll say, “Enjoy your meal.”
But if I specifically emphasize the stress—“Wish you enjoy your meal”—it might not just be plain politeness; it’s probably hinting to you.
Because every day I see all kinds of different shopkeepers. Some are clean enough, but some don’t wash their food at all. They directly use a mop—those floor-mopping mops—in a bucket to wash potatoes. Whatever’s disgusting, they just do it.
But we can’t tell you that outright, because we’re afraid of taking responsibility. If we just hand it to you directly, I’d feel too guilty in my heart, so I came up with this method.
So, my dear gods, wish you enjoy your meal. Can you understand?
