worst that happened to me was a guy who STARTED a fight, i ended up killing him about 5 times before he switched to passive mode, got ina car and tried to run me over. almost got me too until i blew a sticky bomb killing us both, ill take a suicide and killing him before letting him get the satisfaction of a pussy kill like that any day.
He left session after that.
I wanted a new friend to join me in my car to start doing jobs. He thought otherwise and started shooting me, so we started a open deathmatch in downtown killing him 3 to 1. Tried multiple times to get him in my car, but he always started shooting again first. Later I saw a message saying "f*ck you".
Well, if you start shooting I won't be easy going. Still need to remove him as a friend...
I've had a couple of recently added friends do similar, but the opposite also happens.
Yesterday I put a bounty on some guy who killed me as soon as I spawned into lobby. So we traded putting $9k bounties on each other for about an hour. We never came in contact after his first kill because I was able to slip away. Well after about 6 bounties I put on him were collected and some people had collected a few on me I see him drive up to me on map and honk horn. We drove around killing people for another hour or so until I had to leave...new friend request was inboxed soon.
