The context of this sign being in a sushi restaurant would be the key here. In higher-end, “omakase” sushi restaurants, you’ll be served a set of sushi piece by piece as the chef makes it in front of you. Typically you’ll want to eat it as soon as it is placed on your plate.

I’m right handed and still have really shitty handwriting.

It certainly doesn’t subtract from the experience, that’s for sure.
