Talk with the CMs. They often enjoy talking about their jobs, and they'll talk with solos more because no one else is pushing to "Let's GO!" I remember walking up to a CM one day, and just saying "So when are you going to retire so I can take your job?" And then I heard ALL about the job. Sometimes CMs will start things-I once had a CM tell me that a TV station was filming in that area that day "But don't tell the guests! We don't want them to act different." And more than once, when I've been at a CS restaurant during a slow eating time, a CM has sat down to keep me company and tell me about their job.
