Cross service installers need to know what it costs to give an extra 20 euros.

If you ask them to run far away, they will pay 50 more. Why?<br> The original installer has a profit from retail and installation, and if you give 200, even if some people run away and lose money, it is acceptable to calculate the general ledger.
