So, my last job, I was assistant general manager. So, it was kind of my job to know everything. But when I didn't know something, I would politely let them know that I'm going to have to either refer them to someone else or I'm going to have to go and ask for someone to kind of knowledge me on what we're talking about. But the biggest thing with that is just making sure that you're polite, that you're, well not only that you're polite, a lot of it has to do with your tone of voice, your facial expressions, your body language. So it's like, it's more than just being polite and finding a solution. It's like being personable.
