You just received an email from the chain hotel where you stayed last night. Along with offering its gratitude, the hotel is seeking your feedback through a survey–offered in the interest of continuous improvement. You’re asked to provide satisfaction ratings for some very important categories the hotel has chosen. Listed are food quality, staff friendliness, Wi-Fi dependability, room cleanliness, durability of shower cap, and other aspects of your stay that you’re supposed to rate from one to ten. It’s a comprehensive list, but there’s a problem.
