Circle K has had these rolled out in Arizona for several years now, and honestly they're pretty flawless there. I've used the self checkout hundreds of times at this point, and Circle K has a pretty huge selection of products. When it's 2AM and you're waiting to buy a monster, it's nice not having to wait 45 seconds for the one clerk to finish that they're doing so they can ring you up.

I'm not sure why the performance at this stadium was so vastly different.

Circle K in Chicago has them too. Employees are constantly needed to monitor things at checkout. If items aren't clearly separated (which is easy to do out of haste, not malice) it will under-count. The same cashiers at the same store were much faster at checkout than these machines are.
