Europe is big and varied. Where I live (Croatia) I only know of one person who did it and it was only because he practically already accepted another job offer and the current company said "Alright, what can we do to keep you?" (and the salary scaled accordingly). I'm sure there are other similar cases, but overall it's pretty rare here.
