Hahaha, it is very true. Men can be awful at washing their hands. When we didn't have individual cubicles and we all washed at the sinks you could see some people come in and go without stopping to wash and it was fetid. I feel bad when hotdesking now and having to use a keyboard that is shared among many manky people!. Yuk.
I think one option is the way to go for sure. Three is mental!
