Xel gives him a narrow-eyed look, snatching the peel with crust away before it can really fall. "You forgot the sauce," he says in a this is going on your permanent record tone. "But since you were quick, I'll leave your punishment at fixing whatever disaster you just created back there. And explaining to Iago-san why you decided to go into his bar while he was away and take his good rum to be set on fire in a dish no one even ordered. Be back here in three minutes. No excuses."
He spreads the tsume sauce on the crust himself (which isn't ideal, since putting it on before the baking would have changed the texture of both sauce and bread), puts down a checkerboard of small squares of toasted nori, drizzles more sauce on for stickability, and takes out the rice stick. After spreading a layer of sticky rice over the nori, he makes a nice if careless pattern of banana and eel pieces, drizzles another drizzle of sauce over the whole, and sprinkles slivers of toasted nori over everything.
Banana-eel sushi pizza complete. He looks up to see where Rincewind is.
Well, it's more that he's disgusted at how the bananas foster thing is just something Dave decided to do to get use out of the banana peels but Rincewind is taking it seriously, especially since the banana peels are meant for him. n,n;;;
