If I'm in an event and someone wants 1 or 2 HRs I might do it, but if it's another mode or they want me to quit that's a no.
Just today I had a guy ask me in the event to quit because "he was 11-0". Meanwhile I was like 3-1 at the time and I got a game right away so I called out the BS and made him quit after a few runs scored which obviously wouldn't have happened if he was actually 11-0.
I've also had two people ask for a quit because they were "a win away from WS". I knew they were both lying and I found out offer the game that they were both in the low 800s so I'm glad I didn't give them a free W.
