Bro, I went to Arby's to get the same thing years ago.
When I asked for it, they looked at me like I was on crack! The cashier said, "Uhhhhh, we don't sell burgers."
I said, "I just saw the commercial last light."
She said, "Nope, we don't do burgers... not since I've been here. Can I get you anything else?"
I was like, "No thank you... sorry to bother you."
I don't do Arby's at all.
