A silly little thing but being non-smokers I pulled the cigarette-stubbing 'grid' out of the ashtray so it's of more use as an 'odds'n'ends' holder. We can retrieve things from it more easily now, so it gets used more to put things in that we want away from prying eyes.
Sadly, to some people, even small change for the car park can be a temptation if in full view.
