I hate door handles in toilets. Public toilets always have this weird thing where they put the handle on the inside, so you don't have to touch it when you're going in, but when you've just washed your hands and are trying to get out, you've got to touch the pissy, shitty handle, undoing the whole point of washing your hands.
I keep a spray bottle of dilute bleach in the bathroom that I spray on the door handle, toilet handle, taps etc.
