This is a HUGE problem starting in schools where we use a grading system that says C is average but expect our children to get all As. It irritates me more when people review books. Look on
Amazon. How much literature is truly 5 stars? How often do you come across an equivalent to To Kill a Mockingbird? We have lost our ability to appreciate a nice, perfectly acceptable performance. We are using a nuanced rating system but turning it into a GO/NO GO test. You are perfect or a failure.
I agree talk to your service team the first night. But I would state clearly, the only way I will find the service Excellent is if I never hear about the survey or how Excellent the service is.
