We have 2 recurring customers that are vision impaired (there’s an apartment building for people with disabilities nearby). We help place their orders, as we would with any customer that needs help using the iPads for other reasons.

Vision impaired people require the same help reading the menu at any other coffee shop, so it’s not any different. In fact it might make it easier on them because they don’t feel like they’re holding up the line. If one of us guides them through the menu on one iPad, other customers can still use the other iPads to order.

On a related note, I did notice that our visually impaired customers have a phone app that I believe scans and reads the text from the screen out to them. Perhaps we should have our own text to speech option in some future version.
