More likely the IT support will come from the company that makes and installs the kiosk... not from Wendy's. Training in the use of the kiosk and troubleshooting would be a new job for sure.
Panera's has the self order kiosks- I tried them out in Wilson (can't remember if Charlotte's has them yet).. really liked it. Less nerve wracking for me in trying to hear and having to deal with people in general.
They did have at least one register open though- for people who likely didn't like the technology.
