Unwelcome behaviour is reasonable in a regard.Imagine a foreigner dressed like shit, in dirt, unshaven and smelly.Is there any way he can cause a general sympathy?Imagine on the other an attractive foreigner well behaved, good dressed with money in his pockets. How is he possible to cause any dislike?Even the drunk English staggers are welcome as long as they leave money.Appearance is the reason foreigners from Germanic countries are highly welcome everywhere.
On the other hand many Germanic countries have problems with Slavs, Balkans and even Mediterraneans.They discriminate obviously.There will be very different treatment for the Russian oligarch compared to the average Igor.The same Mediterraneans from high classes will get treated differently than those from villages and low classes.Face, conduction, haircut, clothes, shoes play important role how you will be categorized from day one.IQ counts as well.Also knowledge of the language and general level of attractiveness.
Even if you have all this you may find it difficult if your country's culture is regarded as shitty.
