Rough Around the Edges
Exactly. The customers were already "disturbed" so that ship had sailed. The server wouldn't have had to wait on a customer who was made to leave either, so that "protection" was a non-issue. The only thing Iomiller proposes that was actually at (speculative) risk was a "fake complaint of poor service" from the racist customer which as we've explained wasn't a real threat to anyone.
Also, fake complaints from bitter customers, or angry exes of employees, or even people who get mixed up and leave a review for the wrong place - these are a part of life when one manages, owns, or is otherwise involved in the running of a restaurant. You can't prevent them outright, not anymore than you can prevent every single germ in your vicinity from touching your skin. To quake in such fear over the potential for ONE bad bs review, to the point that you publicly accommodate racism, is insane. I'm cracking up at the very notion.
Also, this is Olive Garden, lol. It's not some exclusive five-star joint with a reputation to maintain. It's Italian Eat n Park. (And by Italian, I of course mean "Italian.") One bad review from a crazy person is just going to amount to screaming into the void, especially if the manager were to get ahead of it by filling out an incident report for corporate.
