I find it interesting that what supermarkets tend to put behind lock and key varies by neighborhood. For example, my in-laws live in a somewhat bad neighborhood. At the supermarket closest to their home cold medicine or other products that could be used to manufacture methamphetamine are locked up.
Marathon Girl and I live in a county with one of the highest birthrates in the nation. When you go to supermarket nearest to our home, condoms, other forms of birth control, and pregnancy tests are kept behind lock and key.
I never thought going shopping would make me long for the days when stores never locked anything up and simply trusted people to buy whatever they needed.
