go into the post office and look where it will be positioned and how long the queues are, the last time I went to the post office i was waiting for over 5 minutes I ended up reading a leaflet on passport application because I was bored.
I would use a bold question to grab the persons attention; maybe something like this;
WHO DIRTIES THE CARPETS IN YOUR HOME?
a clumsy child with their fruit juice?
hubby with his morning coffee?
your pet dog after their morning walk?
or Auntie Mabel with her weekly sherry?
