I was trying to be more teasy/funny than hasrhly making fun. I guess tone doesn't come across well in written text. Sorry if you took my comment that way though.
I was, actually just trying to point out something which hadn't been mentioned yet in this thread.
When I talk about accent and appearance (demeanour would be more apt actually), I'm just trying to point out that a lot of rich expats may be harassed more than a local by the trapitos, and have less chance of saying no.
Not all expats are rich of course, I'm sure some live on the equivalent to the Argentine minimum wage, I know some of them personally.
But for the most part that's not the case. And that's probably the origin of me satirising the 'rich expat' so offended by the peasant forcefully asking for 10 pesos (27 US cents).
Maybe I'm wrong in doing that. Maybe not.
Beyond that, tourists and xpats are always bigger targets in their adopted locations, they somehow always standout a little.
In any case, hope that explains my comment a little better.
Cheers!
