When a tile installer only installs the tiles which require no cuts or other work to fit. This generally includes open floor areas and wall areas away from other walls, fixtures, drains and objects where the tiles need to be cut. The worker quickly installs these easy tiles and then attempts to convince the boss, customer or job site supervisor they have accomplished a great deal of work and require some form of upfront pay. They then leave the job site with this money and never return to complete the difficult part of the job.
Job site super> Did Alex finish the tiles in the bathroom?
worker> Nope, that bastard did the Romanian lay!
Job site super> I knew we should have paid him after he finished
