This is the reality of companies like Microsoft - even apple.
When I was in the Microsoft store - there were 10 microsoft representatives simply walking around and talking to customers if they wanted to buy something - most of them were idle. But for repairs, they did not have a SINGLE REPRESENTATIVE at the store. So they want to sell you stuff - but don't want to repair anything- and don't want to take responsibility of basic design issues- probably not good business model. So if you buy $ 3K surface book which has a design issue - you are stuck!
If anyone from Microsoft is listening, this is the store in question-
