I lined up at the WTMD, then was directed to the scanner, so opted out. Male assist put on new gloves, then swabbed them for explosives. The gloves tested positive and were fresh out of the box. Had to get a supv to clean the scanner and open the cabinet for a new box. He said that these gloves (made in Malaysia) were causing a huge number of positive scans for explosives, and he hoped someone in DC was paying attention, as this was a huge waste of taxpayer money. I bit my tongue rather than pointing out an even bigger waste of taxpayer money standing right in front of me with his hands in my pants.
