You see a person that was standing right in front of you. You didn't know him, but he say "This is a robbery." The gun was fake. He meant as a joke to see your reaction. You thought this is your last life as soon you close your eyes. You heard no gun sound shooting at you, so you open one eye and see a bang word out of the gun. He laugh and you were not the kind of person that take it seriously.

He doesn't have a name so you can call him Delivery Guy
