It's a seemingly simple instruction, but you'd be surprised how many people can't understand it.
You give them a ticket to sign in the "Bottom right hand corner please" and they go all over the place, you keep telling them, but no, they just go further left! The last bloke started on the top right, then down the bottom before finally finding the right place at about the 5th attempt. Yes, there's more than one space: That's why I tell them. Why can't they understand something soooooooo simple???
And remember - These are the people that build and maintain your houses and roads.
