(With 1-10 scales often the 9 and 10 scores are considered equal as success and 1-8 all indicate failure.) It's misleading to customers because responses like 4/5, which are presented with positive descriptions, count as negative marks against the staff or business.
The service guys at my local VW dealership are not shy to tell you that only the 10's count and ask when I pick up the keys if there's any reason why I wouldn't respond to survey with all 10's. Personally I think this is stupid because nothing in my life is all 10's.
