I’m looking at a listing for a ¼” to ⅝” screw adapter, for which the seller warns that I should “please allow 1-3cm error”.
A 3cm error would mean that a ⅝” screw could result in a screw thread anywhere between 1⅘” and… minus half an inch, I guess? (I don’t even know how to make the concept of negative lengths fit into my brain.)
I suppose this seller could send me an empty envelope and declare that it contained an infinitesimally small adapter. At which point… I’d be the one that was screwed!
A special level of accessibility failure on Egencia‘s mailing list subscription management page: the labels for choosing which individual mailing lists to subscribe to are properly-configured, but the “unsubscribe all” one isn’t. Click the words “unsubscribe all” and… nothing happens.
But it gets better: try keyboard-navigating through the form, and it’s hard not to unsubscribe from everything, even if you didn’t want to! As soon as the “unsubscribe all” checkbox gets focus, you get instantly unsubscribed: no interaction necessary.
