I have to wonder why they quit making businesses lock up spray paint?Agree...but this has been going on for decades. 40 years ago dental offices were getting broken into for nitrous tanks. Whippets have been a thing forever...as has glue and paint sniffing (huffing). Look for people with gold paint around their nose and mouth...they are zombies and have no brain cells left.
I just object to making life difficult for the 98% of the population (like needing a Rx for Pseudoephedrine in OR until recently). Bad idea to limit sales to minors? Maybe not, but next they will lock them up so you need a manager with a key to get to them.
