Cooks don't do dishes. All dishes will be cleared away that evening. Of course you may opt out and go to a restaurant. Be courteous and let the group know sufficiently in advance. The cost of the meal may or may not be taken out of your shared expenses.
Breakfasts are a more or less cooperative effort.
Somebody makes coffee, maybe brings back some bagels and a paper from the store. Food in the house and refrigerator is there for everybody to use. Special diet food items of individuals are of course off limit. The guest policy is such that we all want to enjoy a peaceful and harmonious weekend. Day-guests are ok within reason.
