If you run a rush delivery company, expect that the customers will be rushed.
If you run a health food restaurant, expect that your customers will care about the ingredients you use.
If you run a preschool, expect that your users will act like little children at times.
If you offer urgent consulting services for clients in trouble, expect that they’ll be stressed and want you to work all night.
If you treat people with mental health issues, expect that they’ll not always be patient and long-term thinkers.
Sometimes, we get what we expect and still complain about it. It’s a feature, though, not a bug.
