Link to recent quick-link thread: Quick link question

Minor break in the otherwise routine commute yesterday. On the way home, shared an elevator ride with a young commuter on a... oh... early '00s Trek MTB. Usual chatter about the great weather that spoiled us over the weekend, blah blah, then I saw it. "HEY, your quick-release is open on your front wheel." It was not just open, but unthreaded almost far enough to get past the lawyer tabs. She had no idea. And didn't know how it worked, like what was mentioned in a recent active thread about QRs and lawyer tabs etc, she kept wanting to use the QR handle like a "wrench". Two-minute primer on proper QR usage after we stepped out into the lobby, and she was set, and grateful. Didn't want to think about what kind of day it could have been otherwise.
