I went to a new sushi place last night and ordered the sashimi deluxe. The waitress came back with sushi deluxe. I've never heard of someone sending back sushi. I didn't want to offend the chefs, who were five feet away. And I figured had I returned it, they would just peel the fish off of the rice and send it back out to me. So I ate it, no big deal. But for future reference, is it okay to send back sushi because of the waitress's mistake?
