"Ah, I see. So this would be your first job ever? Hmmm..."

"People usually come in here with something specific in mind, or are totally clueless. Usually not too many in between. Your job is to find out what they want and sell them as much of it as you can. Keep 'em happy, so they come back and tell other people about this place too. Sounds easy, but in this line of work, it can be tricky. The key is knowing the merchandise forwards and backwards, which will take some study. If you're willing to do all of that..."

He shrugs. He knows it sounds a little intimidating.

"Then I can give you a shot."
