My grandmother doesn't know the difference between an "address bar" or "search bar". Recently she got an email from her insurance company telling her to go to their website www.whateverinsurance.com and click "sign in" and then click "my account" and update her credit card info. The email had the url but it wasn't a link for some stupid reason. She goes to her browser and types in "www .whateverinsurance..com" because her eyesight isn't very good anymore and presses enter. Then instead of giving her an error saying the website doesn't exist and she should re-try entering it, it goes to a Google search page! She clicks "sign in" but her password doesn't work because she's on Google instead of her insurance website. So I get a call and have to figure out why her "insurance isn't working".

When I finally get her to her insurance website, she mistypes her password and presses "log in", and nothing happens. Windows is configured with 175% magnification, which means that the "invalid password" div that appears isn't visible on her screen unless she scrolls to the top of the page!

She originally tried calling her insurance company and updating her credit card number by phone, but she couldn't enter her credit card number fast enough and it timed out and told her to go to the website instead. WHY DON'T THEY TEST THIS STUFF???!?

Sorry, I went on a tangent there. I get irrationally upset by this kind of stuff.

Google Maps is a good example of this. Like the original text box you were shown was searching for an address but enough people typed business search terms that eventually they just implemented that feature.

The Ansible vault is a bad example of this. They have a little command `ansible-vault` that lets you manage encrypted files and strings. If you run `ansible-vault edit ./nonexistent_file` it tells you that you meant `ansible-vault create` and vice versa but doesn't just do it despite the user intent being clear. This ultimately lead me to just patching it to do the right thing.
