Directions: Read the case carefully and decide which is the best “subject line”.David will visit China and attend a technology conference in Shanghai. During his stay there, he will also visit two local clients for product demo. 5 days prior to his arrival, one of the client visit has been cancelled. In addition, he will also check in another hotel since the formerly booked one is not available anymore. As David’s counterpart in China, you need to inform David about this.
