Restaurant Tells Diners To Eat Everything On Their Plate
Chef Yukako Ichikawa will offer a 30% discount to patrons who eat all the food they have ordered, and will kindly ask those who don't clean their plates to not come back. "Finishing your meal requires that everything is eaten except lemon slices, gari (sushi ginger), and wasabi," says the menu. "Please also note that vegetables and salad on the side are NOT decorations; they are part of the meal too."
You're not treated like an asshole because you're full. You're treated like an asshole because you obliviously ordered more food than you wanted to eat. And you get treated like an asshole again because you've become defensive and indignant about it, regardless of whether you're oblivious or disingenuous about your obliviousness to your wastefulness.
So, to be consistent, you should now leave /. and not come back.
