I've been to Richmond Sushi once for AYCE, and I thought the food was pretty decent. But I caught a glimpse of something their waiters did that kinda made me
We ordered, and they were bringing our dishes out one at a time. Then these weird dishes started coming that we didn't order (meats, grilled fish, salad). I tell our waiter we didn't order them, and he took them away.
I kept an eye on him, and he brought the dishes to another table. Those customers said they didn't order them, and he then brought the dishes to yet another table. These customers were too busy talking and eating, that they just accepted the food.
Then the waiter walks away with a supressed smirk on his face, giving a discreet thumbs up to another waiter.
Probably (hopefully) just extra food from other customers wrong orders or the kitchen that they didn't want to waste.
It's really not that big of a deal, and I know it shouldn't bother me, but for some reason it rubbed me the wrong way.
