One guy at our company once had this brilliant idea as well. Go to a bar and validate the idea with strangers. After all, our business idea was related to sports and they would surely be interested. I thought this was a great idea. All three of us agreed it was. Later that night, in high spirits, we went to the bar to execute our plan. We sat at the bar for two hours and talked to a grand total of zero people because we were all afraid to approach anyone and bother him or her about our frivolous, idiotic idea.
