I was going through the security checkpoint at CLT tonight and the guy behind me was selected for further screening. While I was putting my shoes back on, I saw the TSA agent with something in his hand (looked like a battery or something like that) and then overheard him tell the guy "that will be $20." I thought he was joking at first, but the guy whipped out a $20 bill and paid the TSA agent. I saw the agent take the money, put it in a red bag, fill out some paperwork, and then walk off.
What in the world would a passenger be paying the TSA for???
