Sorry - it's just you said you often leave a public loo without washing your hands so I took from that it was a very regular occurence.
I would urge anyone using public loos to use soap and water and wash your hands properly according to guidelines, both for your sake and everyone else using the loos.
Does anyone have a really simple diet plan?
Apparently - Employers are not working people
Hand sanitizer is better than nothing, but hand washing with soap and hot water is far better. You know you can do both?
