The Voodoo Bar has engaged you to deliver a cease-and-desist to another bar: the Voodoo Guitar.
The cease-and-desist letter is in your inventory (the briefcase bottom left). Give the papers to the tiki-masked owner.
Maybe some other employee would take the papers.
Yeah, someone who works for Voodoo Guitar. The employees have name tags on them.
Give the cease-and-desist letter to Spikey the cactus.
