How can I turn away marketers at my door?

[Ring0Rosie]

NEVER, EVER, EVER open the door to someone you do not know.

Look out the peep hole, I you don't recognize them, just grab your phone and walk away- never open the door. If they continue to knock, call the police. There's never a situation where you'd have to turn away a Mormon, JW or a marketer, becuase you should never open the door to talk to them in the first place. Have some common sense and don't put yourself at risk just to be polite.
