"Foreigners? You might think a foreign ambassador would have some manners, and they do, but they also come with or hire their own guards. The VIP service gets the visiting dignitaries who don't have their own travelling retinue, and they're basically the equivalent of the locals who would have received bodyguards here, so it's all the same, except they're even more likely to treat other ponies like dirt because it's not their country, after all."
