This is a simple place for your characters to consume food and drinks – either raw directly from a garden or well done from cooking.
If you don't have a Bench characters will eat and drink only if they get really hungry or thirsty.
Icons in the top right corner will become red which means characters suffer from negative effects such as slower walk.
If you have a Bench available then the "consumption" job is available for your characters.
If you will put it as top priority job for the character, they will go to eat whenever the hunger/thirst is lower than 1/2 of the maxium.
If you will make the job as least important it would automatically trigger when the hunger/thirst gets under 0.
