If I'm not sure the answer of a question, depending on the circumstance, like if it's on the phone, I'll usually say, hey, that's a great question. I'm not sure at the moment, but I can certainly find out that information for you, or I can refer you to someone who would have that information. If it's in person, I'll usually kind of say the same thing, because I always want to try to find the information, but I'm not going to pretend like I know the answers to questions that I'm not sure about. It's best to let them know, hey, I'm not 100% sure. Let me find that information for you and get back to you as soon as I can.
