One night, a few co-workers at the computer data centre where I work stayed late and we all started to get hungry.

We decided to order in food by phone, but our boss thought that, since we work with computers, it would be more appropriate to order by Internet.

After we contacted a fast food chain’s web site and spent a long time registering as new customers for the delivery service, a message appeared on the screeen: “Thank you for your business. You will be able to order food in three days.”
