I don't like to racially vilify anyone from any particular country Frank, I like to think I'm a universal racist, but this guy was Greek, and in my limited experience (Melbourne has the largest Greek population outside of Athens) Greeks will ALWAYS try to lowball you.
The most embarrassing thing I've seen was an old Greek woman at the checkout at Aldi, holding up the line while trying to haggle the price of her groceries with the checkout chick. And two bikes I've bought recently from a Greek guy have both been POS, with lots of missing parts that were pictured in his for sale ad on FB, but I never received? WTF? It takes all kinds, I guess.
