I was not there nor do I have anything against energy drinks and handing out free samples, but maybe someone was concerned about what it was that was being handed out to kids. With all of the things on the market lately, who knows what you are getting. Most of the stuff is high in caffeine, guarana, taurine, etc. Would you have the same reaction if they were handing out free smokeless tobacco samples, or free cigarettes? For the tracks, sometimes it not an easy decision to have someone handing out samples, but you will see energy drink samples being offered at nationals in both sanctions, and some are sponsors for some teams. Maybe we should wait and hear the other side of the story, if there is one.
Ultimately, if they are free samples, you don't have to take them.
