Either keep playing or quit. Don't pro long the game or give up completely which is what this guy did. I accepted a friendly quit the day before this one when I scored 3 in the first inning. I didn't feel like granting this one.
I hate denying freindly quits always feel like I'll get screwed and lose. especially before the first pitch is thrown
I usually spam O to decline as quickly as possible if the game is at Shippett
