Flash freezing individual fish feels a bit different than taking out that (presumably thawed) fish, using it to make sushi rolls, and then refreezing it.
Edit: My perception was obscured by disgust and I didn't realize these are California rolls and don't have fish, but the point stands. Frozen rice and frozen avocado are fucking gnarly. Frozen avocado especially is a sin.

Love that, I do the same. If you want to spread a bit of cheer though, I also tag good behaviour or people that sound like they could use cheering up so I can remember to say something nice next time I see them.
