Last night at LIH, I picked the wrong line and ended up in front of the scatter box. The TSO directing people into the box was actually quite polite and professional and pointed out the option to opt out, which I (as always) did. Nothing unusual about the whole process -- until the TSO doing the pat-down asked at the end for my BP and started copying my name and other information into a log. I asked him what that was for, and he said it was "a receipt that we did the pat-down". Hmmm, a receipt? Doesn't make any sense to me. I have probably opted out about 10-12 times since the program started and my information was never recorded. Has anyone else seen this happen?
