I'm at a conference today up in Boston. Great content, but they do this speed dating thing with the vendors. Instead of walking up to their booth, you rotate around the room and get a pitch.
My favorite game to play is "stump the sales engineer". I got one today that was perfect. I said "if I have control A, B, and C, why do I need your product?" SE kinda looked up to collect his thoughts, then smiled and replied, "yeah well I guess not."
Great to win "stump the SE", but even better when the SE admits it and shakes your hand. I will definitely be buying him a drink tonight.
