I was just paying a bill online.
I had loading images turned off in my browser.
So I get the checkbox captcha thing, and checking it is not enough, so I have to click on taxis, etc. Which didn't initially show because of images being off.
I eventually did turn on images for the site and reload it. But at first, I was like "wait a minute, why should I have to have images on to pay a bill?" and I clicked a bunch of things I'd never tried before to see if there was an alternative. It appears that you have to be able to do either the image captcha or some sort of auditory thing. I guess accessibility doesn't include Helen Keller, or to someone who has both images and speaker turned off (which I have done at some times).
Maybe this is hard for someone younger to understand, but when I was first using computers, many had neither high quality graphics nor audio - that was a special advanced thing called "multimedia". It feels like something is severely wrong with the world if that is now a requirement to interact and do basic stuff online.
