Some article somewhere said the staff there felt threatened or uncomfortable or some other crybaby term. She (the manager) also made clear that they only asked Sarah to leave, not Sarah's entire party, and they did not "kick her out" but asked her to leave. She minces her words like she minces her onions.
She is probably trying to do some damage control, after getting a better idea how stupid she was.
Asking someone to leave IS kicking her out. Do you use a Ginsu knife to mince your words, jackass Shelia?
