Dunked box

I wanted to order the new all star dunked box, but the lady at the counter gave me attitude about how I should it okay cool, on the screen it says a specific price when I try to pay that price she fights with me telling that it’s not the price on the screen , then tells me to use my phone to order I tell her it’s at home then she tells me to leave kfc because I’m not “serious” we went back and fourth and didn’t want to call the manager I ended up leaving
