"Because acetone is an ingredient used in the illegal manufacture of methamphetamine, we recently implemented a policy that a valid ID must be presented to purchase acetone-containing products such as nail polish remover. Our policy also limits the sale of these products in conjunction with other methamphetamine precursors and is based on various regulations requiring retailers to record sales of acetone."
Also, now you're not allowed to buy more than two bottles of nail polish remover a day. No big deal, unless you're having a serious nail art party at your house, in which case you'll also need a variety of respiration gear and probably some plastic tarps. Which is, of course, equally suspicious. (StyleList)
