What exactly would you like them to do? Detain the miscreants? Speak to their parents? Arrest them? Call the police? Confront them? Hire armed guards? Put up a fence? No-loitering signs? You know, it's not their job to fix problems. They pay taxes for that, and it should be fixed and addressed by the local municipality, and until that happens, I think it's brilliant that free individuals find peaceful methods at resolving their own problems. If that happens to move the problem elsewhere, then that's also fine. Either that elsewhere is a concentrated spot where it can be targeted more easily, or another convenience store that can do the same (or expect the police/municipality to fix).
