Serious question, really? Like when you're just having beers with your friends? Why? Does it make your friends feel uncomfortable? What's the benefit to you?
I mean work/project meetings, not "social gatherings". Essentially, when an encounter serves more that just a social purpose and information is shared, I either want a record of that meeting (information) to be kept or for that meeting not to take place at all if there is nothing noteworthy (again, does not apply to meetings that have a predominantly social function).
