The burger wars are hotting up again in France. We guessed it was only a matter of time before Burger King fired back after McDonald's last week erected a cheeky road sign advertising that it was 258km to the next Burger King drive-thru.

The fast food chain's agency Buzzman quickly put together this little film, in which a couple notice the sign and indeed drive to the nearby McDrive. But, there's a twist -- they're only stopping there for a coffee. Because it's a long drive to their nearest Whopper, 258km further on.
