Kiosks of any sort can vary, from fast food to grocery to other types. There are some that work well and make self service far faster and easier, and others that routinely have issues. I've never used McD's, but I have used Sheetz a lot before and it flows very well both in displaying the options as well as suggestive selling that isn't in your face and disruptive. As for groceries, Publix has always been perfect for me, while some others not as much. Walmart's is 50/50 on if it will work okay or have some issue.

I wonder if there's a list of what manufacturer supplies what kiosks and a correlation can be made.

Outside of the ordering, McDs has never been the best, but as they've dropped in quality to drive profits and still meet the demand that persists regardless, so have others. My favorite used to be Burger King in the 90s, but I will go to McD instead of stepping foot in a BK at this point, that's how bad they are.

And the stupid thing is, none of them are doing anything much different. The quality doesn't have to be this low in food and service. I can only assume the bottom line is greater if they sacrifice everything needed to keep standards up and maintain just enough to keep a minimum demand flowing.
