Bob had had plenty of problems with his old computer. He said he'd buy the insurance. "You probably want us to make recovery disks, too," said Joe. "If anything goes wrong, you'll need them to restart your computer. The insurance doesn't include the disks. We'll make you a set for only $30." Bob rolled his eyes. He said okay. He gave Joe his credit card. The grand total was $713. Joe said to come back in two hours. The recovery disks would be ready by then. Bob returned three hours later. "Just a few more minutes," said Joe. One hour later, Joe gave Bob the disks and the new computer in a black cardboard box. He didn't apologize for making Bob wait. He didn't thank Bob for shopping at Office Stuff. It was 9:20 p.m. The store had been closed for 20 minutes. A man was already vacuuming the floor.
