2ft normally for me and those I play with.
What I don't like is, for example, if I have a 5-10ft par putt and my oppo concedes it, then expects me to concede his/her 3-5ft birdie putt.This trick won't wash with me, I'm made of sterner stuff.I don't like someone trying to force a choice upon me. It is a deliberate tactic and worth being aware of. Of course me being so shy and timid I don't give them a roasting in chat. ;o)
