Chipotle: Slowdowns and operational changes - what's going on?

Just wanted to get a pulse on what's happening at Chipotle. Over the last few weeks, I've seen some weird operational stuff. Like, certain menu items are sometimes unavailable even though it's not a supply chain issue we've been told about. And the speed of service seems to be struggling, even when it's not super busy. My manager is tight-lipped, but there's a definite buzz among the crew that something's up. Are they testing new efficiency measures? Is this a precursor to something bigger? I'm starting to feel a bit uneasy about the stability. Has anyone else noticed these kinds of subtle shifts or heard any rumors about what might be driving them?
