I was a regional manager for a bank and had to call a sample of customers for feedback on service in my branches and ask them to score out of 10. Most people would say 8 or 9 and when I?d ask what the staff member could have done better to get a 10 they?d say they couldn?t have done any more but they would never give a 10!

The scores counted towards the staff bonus scheme so I?m sure that?s why they ask you.
