I deleted breakfast, dinner actions on my schedule. Now it looks like they have free time for the whole day (which is not correct, in my opinion). Guests now have only Eat action, but if they hungry, they still go cooking for themselves, not waiting for chef to cook (which is also not correct). Maybe, chef should cook while guests entertain themselves in their free time (now it’s the whole day according to schedule). But in this case, chef should wake up at 4 am and prepare food.
UPD: I set chef to cook at 4 am, and the main activity for this time is Cook. Guests still should sleep. The chef in my game just didn’t wake up. Started cooking at 7 am when guests should eat.
