Carole and Richard go to IKEA knowing what they need and where the products are located in the large warehouse section of the store. On a previous day, they had walked through the showroom where they were forced to follow the path dictated by the store. Instead, today they bypass the showroom upstairs. They go directly to the warehouse and use an automated kiosk to quickly locate the goods they want to purchase. Their goal is to get in and get out of the store as quickly as possible so they can move on to other errands across town. Which McDonaldization component is best illustrated by this example of Carole and Richard's goal for today?

Control

Efficiency

Bureaucracy

Irrationality of rationality
