I had just got done robbing a convience store in GTA V: Online and climbed to the rooftoops to hide from the cops. Well after they called off the search, I hear a motorcycle pull up and knew it had to be a live player nearby. I was looking at the laptop at the time, but I can tell when there is a live player or a NPC driving just by experience. Anyways there are two guys on this motorcycle and they just park in place trying to find me and kill me. Well the driver decides to throw a grenade in the direction he thought I was at but I ducked behind cover while on the rooftops and shot at them from the back with my grenade launch. One hit and I blew up their motorcycle, killing both of them in the process. I could hear one of the guys grunting over the mic so I turned on my mic, started laughing and said "serves you right, D-Bag!"
