Dunno where you live, but according to this (https://www.epilepsy.com/stories/shedding-light-photosensiti...) from a US charity: About 3 to 5 percent of the 2.7 million Americans with epilepsy (approximately 100,000 individuals) are photosensitive. That's a lot, but the chances of one walking in to that bowling alley are likely negligible. Photosensitive epileptics are highly likely to be aware of their condition and avoid risky environments in any case.
