This isn't on you at all.
@MarkG too, restaurants have always served sharing dishes in prime numbers, it's to make you buy more. Oli's used to provide 5 leaves in their starter wraps, which was tricky between 4 - we asked for more an got 1. It's either worth it or it's not. It's your choice.
What I will not accept at all though, is that you go into restaurant that serves Italian gnocchi, Korean chicken and Vietnamese whatevers at all. What the f**k, you expect something good? It's fusion, the worst of all the worlds.
I say this as a man who has wrestled a Joburg servitor who tried to put fucking mayonnaise on sashimi to the ground.
