I heard a great story from Harvey Mackay, a world-renowned author and speaker, who talked about how he used to love standing in line at the Starbucks counter at a tradeshow because it was filled with his potential customers. And every time he waited in line, he could talk to a few of the people in front and behind him and generate some leads. It struck home for me (which is big because I absolutely hate waiting in line) and I have since landed several customers, as well as my largest customer ever, waiting in line at the Starbucks counter at a tradeshow.
