You come up to a 4 way stop. You want to turn left. Across from you is a newer model Blue Dodge Ram license plate number 425-JHT with some hick looking dude on a cell phone. He was there first. After stopping, he flashes his brights at you to get you to go in front of him. What do you do?
A: Acknowledge the gesture and proceed through the intersection?
B: Wave him off and wait for him to proceed?
C: Piss the guy off by folding your hands and stare at him?
