I gave this a shot and I was able to get through the process of making a dish and after a bit also figured out I needed to plate it before serving, but when I moved the dish to the customer it just got stuck there. I'm tryna serve grandma her nigiri and she's covered in it now since I just kept making more and sticking them on her hoping it'd trigger the "serving". I tried placing it in front of her but that didn't work either (it didn't get stuck, but it didn't do anything). I tried with other customers and it's the same. The art is really nice so if you let me know what I'm missing and how to serve a customer I'll give it another go!

I don't seem to be able to make anything, but I hope you had fun making the art.
