You're standing in line at a coffee shop when you spot a shiny coin on the ground. You bend down to pick it up, but a big black boot stomps down on it just before your fingers grasp it. "I wouldn't do that if I were you," a deep voice warns. SOMEONE PLESE WRIGHT ME A STOR

You look up at a furious man glaring at you. Tattoos crept up his neck and his face was covered in scars as if they were trophies showing the fights he’s how.
Describe the coffee shop and how the man walks and talks. His voice is deep and raw and tells you to come with him. You could then make him warn about something from the future like a terrorist attack that will happen in 5 mins and it’s your job to get everyone out of there. Or he could take you somewhere. It’s up to you just make sure you use lots of descriptive language and similes, metaphors, adjectives and make sure to use correct grammar
