Net Promoter Score for customer service ratings? Ugh.

This “Change My Mind” meme photo shows a smug, smiling dude sitting behind a table with a paper sign hanging down. In the original photo, the  sign contained a provocative statement followed by the words “Change My Mind.” As a meme people replace the original provocative statement with something silly. The words I’ve added are “Net Promoter Scores are inappropriate for customer service ratings! Change my mind.” This is meant as a joke, not as a burden on you to change my mind!
