Sounds like a simple enough question for a simple enough task but not always. A co-worker of mine asked to see a guy's library card so she could sign him onto a public Internet terminal and the guy practically did a strip tease in front of her. He stood at the Ref Desk, unhooked his belt, unzipped his pants only to expose another pair of pants that he was wearing backwards. He then took his hand and shoved it down the back of his pants and pulled out a wallet. He opened the wallet and finally flashed his library card. My co-worker and I just kind of looked at each other in bewilderment. Did he have it stashed between his butt cheeks or something?
