My friends elderly mom went to the game many years ago and was taken away by security after a check at the entrance. Her crime? When they checked her purse, they found an Oh Henry in it. She usually took a chocolate bar with her to give to her granddaughter when she sent to watch her ski, and had forgotten this one was still in the purse. After whisking her away to the "green room" (Oilers security interrogation room), they scolded her, confiscated the chocolate bar, reduced her to tears, and then let her go to her seat. A seat, by the way, which was part of a pair of 20 plus years season tickets. Her son was furious when he found out, but she convinced him to leave it alone and blamed herself for being so "careless". This was pre Katz, and the Oilers leaking ticket holders and struggling to stay alive.
