You're absolutely correct.
To be honest, I've got a belly full of arrogant foreigners, legal and illegal. I know people that work in the service sector, retail etc, and many of these people are the most arrogant, demanding AHs you've ever seen..They come in dressed in the native clothes demanding discounts like they are owed something.
I kid you not, many of these Koreans and people from India come into these store, asking Korean or Indian discounts...No joke. "I buy two, you give me discount".
I've spoke with people that work in these establishments and they'll tell ya, many of these people are not only arrogant, but rude to the bone, and they'll go straight to the non-white help, and demand discounts, or just interrupt the sales people that are already helping others.
To be honest, I've ran into a lot of people from south of the border, that make it really obvious, they hate this country, and white people.
And many of these foreigners that go into business, they'll break every rule, regulation, law and business ethic ever written or established. The attitude is, "I do what I want" and the lying excuse when caught up in fraud or whatever is always, "I don't understand your ways".
You forgot to add that they smell funny.
