To the "spray paint" complainer: there are different laws in the towns to prevent the purchasing of spray paint by juveniles. The companies are complying with the law, as well as limiting their liability for those that use and die of spray paint huffing. Some may lock up the cans, some don't. Lowes had you scan your ID because of the military discount. Happens to me all the time if I go to self checkout. Put in your phone number, then scan ID, then 10% off. It's to check we are the eligible persons, not someone else. You don't have to get the 10% if you don't want, it's not the law.
