I would still argue that no member of that pact had any authority, only the Soviet Union, so its a formality to say Hungary wasnt part of the Soviet Union, even since most policies came from the Soviets.
I think in your example its totally fine, since you make stuff for your own consumption. In this chapter they prepped multiple orders (i dont think he would get 100+ grozas for himself), didn't even get to eat anything and left. She probably sold them to the next customers, and that whats questionable for me. Also he only got paid by vouchers for the thing he himself made.
Or Im overthinking stuff, but this manga makes for fun though experiments.
Edit: you got downvoted for discussing a manga in chapter discussion post on the ani.social anga community? isnt that the whole idea of a discussion post?
The totally Osha complied gyaru restaurant is back!
Is it legal to have a customer cook? Maybe she teached him food safety & hygiene course off screen? When will the safety inspectors raid the place? Maybe next chapter!
Deliquent-turned-good are one of my weaknesses, add in cooking and its just chefs kiss
