That hasn't been my experience at least. And yes, I don't need to have a conversation with a cashier, but I also don't wanna watch someone do something so basic that I can easily do myself. And from my experience, lines have gotten much shorter everywhere self checkout has been implemented.

Additionally I am not suggesting get rid of all cashiers, I just don't want them to get rid of self checkout either. Give people the option so they can use what they prefer.
