Yes only the obsevant realise this if you go to certain countries bargaining is far more ingrained in the culture than it is in the uk. So when you price a job up finish it and tehn expect to get teh full price yuo quoted and agreed on some cultures and indiviuals of course see it as a new bargaining point and wonlt pay in full or expect extra work done for no extra pay.
Once yuo realise this you add the amount that wil be bargained away to the original quoted price.
