This is absolutely a massive issue with it. Apple did this with retail employees back in the day and it was terrible. Employee reviews were based on it, managers had to call customers and apologize if the customer didn't leave a 9 or 10 rating, it was absolutely awful.
One of the biggest problems with it is that an average person, unaware of what NPS is, doesn't understand that giving any rating less than a 9 is essentially giving a rating of zero.
If I have what I would consider to be an average interaction with a business, e.g. I just buy something and leave, no need for support, no problems to deal with, etc., that seems average to me. Based on a non-NPS understanding of a 0-10 scale, I'd say that's what, a 7? But the business now considers this as a failure on the part of the person that helped me at that store.
This is why sales people and phone reps are constantly now asking you to give them a 10/10 rating if you receive a survey, because even if they literally just took your money and handed you change, their jobs depend on you acting as if you had a heart attack and they saved your life by performing CPR or something.
It's honestly a terrible system that produces no meaningful feedback for the company and causes employees to do whatever they can to game the numbers. All you're measuring with NPS is how good your employees are at juking the stats, nothing more.
