(I used to work at a theme restaurant that had a huge, double arch aquarium at the entrance to the dining area. We had staff members who would clean the tanks from the inside in full scuba gear. The tanks were filled with brightly colored, tropical fish.)

Patron: “Oooh! Is he there to paint the fish?”

Me: “I’m… sorry?”

Patron: “The fish. Is he in there to paint them?”

Me: “Oh no, ma’am, the paint would wash off if we did it underwater. He takes them out to paint them.”

Patron: “You take them out? That’s horrible? How do they breathe?”

Me: “Well, ma’am, it’s very quick. We use an airbrush and stencils. It really only takes a few seconds. And since the paint is misted on, it dries almost instantly.”

Patron: “Well, that’s a relief!”
