(WFLA) -- A Florida woman is demanding an apology after she was turned away at a Bradenton McDonald's because of her service dog.

It began when Elisha Griggs ordered a drink at the counter.

"They told me, 'No pets.' I said, 'She's not a pet. She's a service dog.' They asked me if I had paperwork for her. I said, 'Yes,'" Griggs explained.
