Restrooms are for Customers Only

Charity and Mark got me hooked on Restaurant City, a Facebook game where you run a restaurant. You get to decorate it, hire employees, procure ingredients, and serve food. When you get to a high enough level, you also have to provide toilets. You can watch your restaurant operate--seeing your avatar friends cooking, waiting on tables, and cleaning up--seeing other avatars come in and eat and drink. Some of them just come in to use the toilets. Isn't that annoying? Yes, I realize it's weird that I'm bothered by virtual customers using my virtual toilets without eating any virtual food.
