The guy in "street clothes" sounds like he was an enthusiastic stockholder making an attempt at doing some informal promotion but he doesn't appear to have really got the hang of marketing. Maybe his follow up was to place the empty can prominently on the sidewalk as another means of advertising. This method has been suggested by some of the more committed stockholders as way of getting the good news out. When you buy the Cessna out of your trading profits you should ask Jerry and Lily if they would like you to do some sky writing over NYC in support of the new billboards.
