No petting the blowfish, people.
I just had to take a photo of this warning sign. It wasn't easy to photograph, 'cause I had to convince a rather dense person to get the hell out of my way. I tried to convince him to turn his head so I could shoot through his ear canals, but he didn't get what I meant. I finally got him to move by convincing the person in the next seat to bring out something shiny to distract him. It worked. I'm not kidding.
