Typically not a good sign...
When a conversation over lunch begins with, "Since HR isn't here..."
The interaction went something like this:
[man] "would you dance on that table and screech like a dinosaur [he illustrates by braying a horribly obnoxious sucking/screeching sound] if I gave you $100?"
[woman] "Sure."
[man] "Would you bite the head off of a scorpion for $10,000?"
[woman] "Only if the stinger were removed."
[man] Adds qualifier, "You have to hold the claws out like this [stretches imaginary scorpions claws out into a horizontal line] and gnaw that bastard's head right off."
[woman] "Now we're requiring tax free payment... Yes, I would."
[man] "Would you eat the corn out of your own shit for $1 million dollars?"
How it escalated that quickly I'm not sure but I won't finish the conversation and let you draw your own conclusions.
