So, in the area of handling difficult customer interactions, I would say, you know, you want to start off by hopefully avoiding them before they even happen. You want to be prepared, you want to be knowledgeable, you want to understand what the person is looking for. If something that they didn't approve of occurred, you kind of want to slow things down a little bit and break it down and figure out what the issue might be, and figure out a way to resolve it to their satisfaction. And I think the slowing it down and thinking things through is very important, especially if the customer is sort of upset and, you know, maybe they're not explaining things clearly. But, you know, you need to have a very clear understanding of what the issue might be. You also want to kind of control the situation, so if someone's feeding you too much information too quickly and asking for answers before you're even prepared to answer the question, you have to sort of take charge and then just, you know, slow it down, do it piece by piece so that it's done correctly. And I found that's what good customer service people do, you just have to understand before you try to explain something you're not clear on, so I don't anticipate that should be too much of a problem, but you always have to be prepared for that.
