Toilet hygiene
When using "trap 1 or trap 2" at work I will hear colleagues come in, use the urinals and go back out without washing their hands. Others will bypass the hand drier, run there hands past the air dryer so that as they come out of the toilets anybody outside will think that they've washed their hands because they can hear the drier blowing. I reckon only 3 out of 10 men wash their hands after using the toilet at our place
