Swearing at them makes it worse…

That's not going to cut the mustard when you're a fucking scruffy bogan from outback 'straya though is it?

So, instead I'd go for the "you hear about all those English backpackers being hacked up in the Australian outback by some guy?" kinda "washed down with a nice Chianti" vibe. Hannibal would be so proud.

PMSL What, with added lip-licking and asking them "Hey, you ever tried eating long-pig..? S'tasty."
