"Yes, hello, WrenchMasters?"
"Yes, how can I help you?"
"I need help learning how to fix my car. How do I change the oil?"
"Oh, well, you just drain the oil, change the filter, and fill up the engine with fresh oil."
"Ah. I see. Well, that all sounds really confusing. Can you fix my car for me?"
"Well, sure... we charge $60 an hour pl..."
"No, I meant for free. It's just that, you know, you guys know so much more about fixing cars having gone through the trouble of learning all that and all. So I figure you could fix it for me. For free."
"Well, I don't know..."
"Oh, no, it's cool, I'll tell all my friends that you guys were the ones that fixed it. For free. See?"
