All I would ask is parents, PLEASE:
Do not let your young or mentally disabled child roam unattended throughout my store. We are not your daycare, we do have some creepy customers, and we do sell porn here.
Once your young or mentally disabled child does begin to throw their inevitable fit in the middle of my store over god-only-knows-what, please leave immediately with said child. No one (the employees or the other customers) want to hear the screams, the crying, your threats, and/or your pathetic attempts to soothe your child that never work. Just take the kid out of the store, where it will be much more obvious to them that they will not be getting whatever it is that they wanted. If they calm down, then MAYBE come back.
Do not purchase products for your children that state on the label they are for an older age range, then come back to the store complaining that your child broke it/it was inappropriate/whatever. Please.
End rant.
