You have misunderstood the article. The problem wasn't the lack of napkins, the lack of ketchup or a problem with the food. The problem is with the customer. Even if you got all of those things correct, they would be upset with some other aspect of their service. If you had brought everything out ahead of time they would have complained "Why have you put so many things on my table? I never asked for any of this!" This isn't a staffing issue.
