When it happens at a party or even it has generally been fine. Only once has it been a "problem" and that was because the person that knew us could not get over the image they have of us from the vanilla world. As they were new to the lifestyle it seemed to throw them off. We have since met again at the same location months later and they seemed better able to handle it even talking to us a bit. Thankfully they seem to not go as often as we do and have time to "process" it as they put it.
Now meeting from folks outside the lifestyle at vanilla places can be a bit trickier. Generally it is like meeting friends from anywhere else if they even let on they recognize you. In fact we had that happen today and honestly we are not sure if we were recognized or not but we did speak to each other as he was working at a volunteer booth. Then we have had folks who could have been a little more discrete about things. Generally though it has not been a problem.
