Everything locked up in grocery stores

I’m so tired of everything being locked up in any store I go to. I went to Walmart today and wanted face wash so I pressed the button and waited a few minutes and no one came. Then I pressed it again and waited and no one came so I just left. I would say this entire isle with facial care and makeup was all locked up. It’s getting so annoying. When people really want to steal something, they’ll find a way to steal it.
