I voted "No" as I (thought I) had not been gifted a cigar by a random stranger. And then, after thinking about it got a an hour or so I realized that I had been gifted a cigar by a stranger -- at the Sosa Cigar Bar at Disney World. A guy sat down next to me and we started chatting and he gave me an Opus X to try...
Must not have been too memorable as I do not really recall the cigar very well. Will probably have to give them a shot again
