Most customers are great, but every now and then, you're bound to run into one who drives you batty.

In the video below, jewelry store owner Cullen Wulf re-enacts a conversation with just such a customer. She fails to understand — or perhaps willfully misunderstands — how appraisals work.

Perhaps his humorous take on the situation will give you some ideas for when it happens to you. And, let's face it, it will happen to you.

Of course, we don’t encourage you to make fun of your customers. And now you don’t even need to — you have Cullen to do it for you!
