Candy Bar

I had an interview at Des Moines University for podiatry school this Friday.  I contemplated giving one of the interviewers the candy bar (as a token of gratitude and friendship), but I eventually decided against this because I felt it would seem unprofessional.  My brother-in-law assured me that I made the correct decision.  Anyways, on the drive back to Denver from Des Moines we were stopped at a gas station.  I went in to buy some sunflower seeds.  I saw the guy behind me grab a snickers bar, so I quickly bought one too and left it there with the cashier with the instructions of how to give it to the guy.  I didn't really stop to look back, and he didn't come say thank you, so I assume he thought it was nice but weird.  He probably was wondering why a complete stranger bought him a candy bar.  Anyways, interesting, and somewhat rewarding (I guess) experience.
