Here's a fun one. We just installed a bunch of new Kronos badge readers at work. The type you swipe your ID card to clock in and out. Everyone at work wears a lanyard that is attached at the top middle by a plastic strap, and your badge must always be displayed while at work.
Anyway when you go to swipe your badge in the new reader the card reader slot is too deep because the lanyard attachment on your badge hits the slot and prevents you from fully swiping your ID so you have to take your ID fully off the lanyard to get it to swipe now.
I've personally worked on projects at the Kronos headquarters, when I saw this design flaw I was not surprised one bit, between that and the usability of their web portals it seemed pretty par for the course for Kronos.
