Me: "So, what's the issue that you're calling about?"
Customer: "I don't really know. My son was having trouble with his computer connecting to wifi, but he's not here today. He called Saturday and you told him he needed me to call to verify him on the account. So I called and I guess I verified it."
(I look at ticket... the customer has just purchased $98 worth of tech support, usually associated with virus removal).
"Do you know what's going wrong on that computer?"
Customer: "No, I'm just calling to verify the account."
