Washing Dishes in Bathrooms Tip

It doesn’t seem like anyone has brought this up in a very long time so I thought it worth repeating.  Players get annoyed when their Sims don’t use kitchen sinks or dishwashers and take dirty dishes to the bathroom.  I discovered that if you bring up the sink menu you can choose sink type. You can choose to have a sink as multipurpose or you can designate it a bathroom or kitchen sink or both.  So all you need to do is set your sink type to bathroom and Sims will only wash dishes in the kitchen sink. I hope this is of help to someone.
