The Stealth Sign Up

Last night I hosted Asian Persuasion speed dating.  It was a great event.  This is one of our most popular events.  There were two more men than women, so the guys had 2 breaks during the night.  I chatted with each of them, of course telling them that I wouldn't be offended if they didn't want to chat.  One of the most interesting conversations was with a guy named S.  It turns out that his friend, who was also there, signed him up for the event and didn't tell him until the night before.  His friend was sure that S would never have signed himself up for it and if he had gotten any more warning that he would have backed out.  By the time he got to me he had about half of the dates under his belt and was having a great time.  We chatted about being out of your comfort zone and doing things that you wouldn't normally do.  I made him promise that if he ended up hitting it off with someone that he would email us his success story.  So, how would you feel if your friend signed you up for something (speed dating or something else) without telling you?
