Handling different customers. I know I'm very versed in this situation, particularly because I've been in the beginning stages of customer service, where you're trying to sell a product, all the way to dealing with different customers when they get products, like for our aerospace, when they get certain products and certain services. Things are wrong with them. I remember dealing with them because I was in a complaints department. And so I handle it with calmness, just speaking clearly. Now, not slowly, because that can aggravate customers, but just clearly so that in using different terms, maybe terms that will relate to them to help them understand even better. I also let the customer get across everything that they have in their mind that they want to, because I believe the difficult customer comes from a place of not being heard. And so when you let customers and people speak and clarify what it is that they're looking for, what they need, and you let them speak, and don't interrupt them or anything like that, and then you come from a place of understanding, you will be able to handle any difficult customer. I don't think there's been a customer I've come across where I couldn't handle, but typically I've always handled it and never needed a manager. I've handled it for other customer service reps as well, where I would step in and try to calm the situation down. But yeah, I don't think that's happened.
