Indonesian: Di Belanda, sudah menjadi kebiasaan saat membangun rumah jika sudah mencapai bagian tertinggi dan atap sudah siap dipasang, pemilik rumah menjamu para tukang bangunan dengan istilah "bir atap" untuk memberi selamat. Sebuah bendera kemudian dipasang di bubungan. Jika pemilik rumah agak pelit, yang dipasang bukan bendera, tetapi sapu.
English: In the Netherlands, it is the custom that, when during the construction of a house the highest point has been reached and the roof is ready for tiling, the client treats the construction workers to so-called "tile beer" to celebrate this. A flag is then placed on the ridge of the house. If the client is too stingy to treat, not a flag, but a broom is placed.
