Today, a customer (technically) came by in a car and brought sushi as a treat.

The "squid and sushi" in the title is actually unrelated—it's a crime prevention safety slogan where:
・don't go with strangers
・don't ride in a stranger's car
・speak up loudly
・run away immediately
・tell an adult right away if something happens
—you string together parts of the first letters to make the phrase.
There's internet slang in Japanese with the verb "hiace" (abduct), but similar to that, America has the urban legend of the FREE CANDY or FREE CANDY VAN—a bad vehicle that lures children by offering free candy...
So all you good kids, don't search for images of that, okay!

Anyway, as thanks for the treat

I cleaned up their car.
