When some shitskin starts begging for change, you take a lesson from Epic Beard Man and tell that nigger to get his shine box.
I want to see this!
Earn your nickel, nigger!
Don't go out of your way to avoid dealing with the nigger. Instead, make it worth your while. While it's shining your Stacy Adams, ask if it's got any warrants. Say you heard the police were around asking about it and then sternly tell it the cops are after it! The fun part is watching it freak out as it tries to figure out which crime it had committed most recently.
