I already set off alarms all the time at stores with these gates. They seem to be set to close completely after every customer enters. Or maybe the ones near me just need their motion sensors adjusted, to be a little more sensitive. Either way, I just don’t stop walking, and usually end up hip-checking it out of the way since they’re still trying to close when I approach. They’re not difficult to open and they don’t hurt. But forcing them open (by just walking through them) sets off the alarm.

I don’t even bother slowing down or acting surprised. I just keep moving to whatever I was going to buy while the alarm blares behind me. It’ll stop after a few seconds, meaning it only seems to go off while the gate is actively being held open. If someone truly wanted to be annoying and malicious, I guess they could just set a shopping cart inside the gate as they walk through, so an employee would actually need to manually intervene and move the cart.
