There's no hard and fast rule about this, but you need to stand out from the AFC crowd, especially if it's online dating or a really hot babe. Either don't kiss and get her mind running over a next date if the chemistry isn't necessarily there yet for a kiss close or kiss her and grab her ass (possibly even finger). If you can pull her home you can also wait to kiss her there. The RSD guys usually either kiss in the bar and then pull her home or pull her home and then kiss, at more rare times they may not even kiss at all but leave the possibility for a next date. Escalate as needed and see how far it goes.
