This is a picture of my kitchen sink, taken not long after I came home from work today:
Don't know how well you can see it, but there is about 2" of water in each side of the sink.
Um, I hadn't run water since this morning, when I rinsed out my coffee pot. The darker muck on the right side of the sink would be the coffee, after having been watered down all day.
Mind you, I don't even have a plug that fits in either side of my sink. I won't show you a photo of the dishes that are not-so-patiently waiting to be washed in my non-draining sink.
Time to call the landlord, eh?
