The Arabs are starting to annoy me

I worked hard on upgrading the KATZAA oil terminal kitchen and dining room near Ashkelon. Got paid 80% of my fees. The rest was to be paid after the actual completion of the building. 

Last night a rocket hit the oil tanks (pic) and black smoke reached 30-40 m high illuminating most of the South. 

When, if ever, shall I be paid? The Palestinian behaviour is starting to irritate me.
