A landlady put up a zero-tolerance drug notice after repeatedly finding empty cocaine bags behind a toilet in her pub.
Judy Boulton taped a message for the anonymous drug user to the tiles of the men's toilets at the New Inn, in Burslem, Staffordshire.
Referring to the empty coke bags, she told the drug user to 'f*** them off', before adding 'I'm on to you', StokeonTrentLive reports.
