Self checkout is generally annoying in a few cases:
* You use reusable bags. In general most systems I've used dislike when you put a bag in the area with the weighing things, so now I have to spend double the time moving items around because they can't just go directly into the bag
* with fresh produce, the cashier will most likely have the most common items memorized and punch in the code without a hitch, whereas I have to navigate a clunky UI to figure out which kind of green onions to charge
* anything involving an ID check is much faster; a human is legally required to be there to verify, and the cashier is already conveniently there, as opposed to a self-checkout register where I have to wait for somebody to come to me
The only issue I have with them is limited area to put your bags. Is the space made for ants? In college I was a cashier so I still have a 6th sense about where UPC/QR codes are and I can buzz through items as fast as most cashiers, however the limited bagging areas are very annoying.
