to be fair though... Those ball pits are full on nasty and we all know that there are a lot of parents who don't think anything of pointing out that their child just lost a diaper in there or wet themselves in there, or got sick in there.
It is sad to think of all the things that we thought were fun as kids may be more dangerous than we really would want for our own kids (lawn darts!
)
obviously that isn't to say never let your kids in there but i am sure a lot of people don't think about how gross those places can be.
