Customer: “My TV has a USB port and the manual says I need something to plug into it to be able to record. A HDD, or SSD, or an STD or something.”

Me: “Oh, a hard drive! Sure, let me show you where they are.”

(I show the customer to the hard drives and we discuss how much space he needs.)

Customer: “So, should I get the 320GB or the 750GB STD?”

Me: “Uh, well it depends on how much you think you’ll be recording.”

Customer: “Well, at this price, I’ll just get the cheaper one. Then, if it fills up, I can get more. My family can swap STDs whenever they need to, then!”
