I have heard in our bigger cities (Sydney, Melbourne) while one zombie keeps you busy at the front door, talkin' BS, the other one (s) try to get in the back door
for a snatch and run...... So, my advice is, if there is someone yackety yacking nonsense at your front door, say no thanks, close and lock the front door, then head straight for the back door and check there as well
And expect the 'unexpected' (Be alert, we need more lerts)
