Hi, when I don't know the answer to something, I'm very honest about it. If it's with a customer, I'd ask them, hi, do you want me to get back to you, if you know the person I believe would know the answer to this question isn't available, or I would give them, you know, my best educated guess, but tell them, this might not be 100% correct information, but I think the worst thing to do is to lie to someone and say, hi, I know this, you know, I know this information, even if you don't, I also think it's not okay not to educate yourself on the subject or the question after if you don't know the answer. So I believe honesty is the best policy, and to search for that information and give it to the person if they're still expecting it, or to find someone who does know the answer to the question, but of course, it's not okay just to lie and say you know the answer, just to avoid embarrassment. It's okay sometimes not to know something, but there are times when, I don't know, I'll get back to you, and then I go and search for the right answer to get the person so they aren't left in the dark and confused or wondering why the person just made something random up.
