Tell them to look at the ones Canterbury City Council use in some of

Last time I was in Canterbury I ended up phoning the council to work out
how to work the b***y machine. And then explained it to the 3 people
who had overheard, and couldn't do it either.

The one next to Canterbury West if you want to wander down and have a go.
