Coffee Grounds Banishing Spell

This is rather quirky person-banishing spell, but does require a little bit of finesse.
To make the spell more potent, and maybe scare them off before even doing the spell, offer to read thier coffee grounds like tea leaves. Don't just be depressing like Professor Trelawny! Actually read thier grounds and be honest with what you see.

Anyway, the spell.
Invite your target over to your home and serve fresh brewed coffee. Offer to read their coffee grounds. When they have left, immediately gather your spell materials.

1. Gather the dirt from your targets foot prints of, alternatively, gather dirt from under a chair in which they were the last person to sit
2. Combine this dirt with cayenne pepper, ground sassafras and used coffee grounds (preferably from their own cup)
3. Sprinkle this on the target’s front doorstep
