Do I need the toilet?

I think this is a question that men (and some women) need to ask themselves before they leave their homes. Near where I used to leave there was a little alley by the side of the car park entrance to Tesco's, and you would see men walking in and out of it and trickles of yellow liquid pouring out into the street.
It really ticks me off when I see some guy standing in a corner peeing, trying to be discrete as if no one can see what he's doing.
Then when he's done what does he do?, he zips up goes about his business, there's no where for him to wash his hands. He goes on the bus, handles money, eats food, and shakes your hand :-(. Sickening isn't it.

So I am pleading with you, please go before you leave the house. Or carry wet wipes with you. I'm sure you understand my gripe, it will benefit you in the long run I'm sure.

Thank you.
