Saw a Haitian once coming back from a vacation. Standing in the middle of the road with a sign that had broken Portuguese that amalgamated to "pls give me money my family dead and im poor from haiti".
The moment my grandfather saw him he just started honking the car horn as loud as possible. The Haitian wasn't in front of him mind you, but the sight of him visibly angered him to the point where he started turning red. After that he went on a rant about LATAM immigrants and how they were "ruining" Brazil (already ruined)
