That first video looks like a totally normal seizure, which may, or may not have anything to do with the phone flash. Most people who have epilepsy are not photosensitive. If its a "scam" that lady is a talented actress.
The ladies working in the nail shop are reacting exactly the same way 99% of Americans do when someone has a seizure. None of them know whats happening, or what to do. This is why seizure education is so important for the general public (and school administrations).
