South Africa is considered to be one of those 'Third World Countries' too but if you look at the wealth in Cape Town you would not consider this country to be 'third World'.
That's because for white people, SA has been pretty much a First World Country,
for the Blacks - a 3rd world. It's still like that for most of the blacks except the corrupt
ones in the government and the super rich affirmative action candidates - as SA is
facing a reverse anti-White discrimination policy right now. SA will probably become
3rd world though like Zimbabwe. Still if you compare service levels in SA shops
and Polish ones, the staff in SA shops are much more polite and usually treat you with
class. Polish and European service personel are quite rude, its improving but its still
bad. I've had some bad experiences in Poland when I visited in August of last year.
If I was to compare the UK, USA, Germany, Japan, South Africa and Poland,
I'd say Polish shop clerks were by far the most rude and intolerant of customers.
