I'm cleaning a house with no bog brushes. There are always streaks in the toilets. 
And several clients have those disposable head brush handles in stands next to the loo, but no heads for them. They just gather dust and get in my way and still nothing to scrub the bowl with!
I carry a designated washing up brush for these sorts of houses, and it requires much rinsing and bleaching before I wrap it backup up in its plastic bag. It's all very disgusting.
What's up with that??
