Except in this case the restauraut would have been able to handle the 5k orders if they didn't arbitrarily have their workers work with their hands tied behind their back. And instead of untieing their workers and appreciating the realization they were accidently bottlenecking themselves they blame the nearby event who caused a spike in foot traffic.

Publicly attacking your users instead of celebrating their success and your new learnings is not what I would call handling it perfectly. I think going for a halo effect strategy where you celebrate how people are using your platform to accomplish their goals will help people understand how what is being done is valuable and want people to adopt it or financially support it. On the other hand attacking people who use your platform publicly can make people apprehensive in using it fearing that they will be criticized too.
