True, as Rich one said, each building is an universe....!
My building is a bare-bones operation, light-years from Antipodean's fancy building. No bringing cars to the front, no chief portero plus assistant porteros, no Chrismas tree in the lobby. As a matter of fact, no lobby, either...!
There are just five units in the building, and our portero is a young guy I often chat with and have come to know well. After six years, I know all about his family, his youngest daughter's medical problems, and his wife plant-selling business.
So, I'd like to give him a good Christmas bonus. I guess a week's salary would be about right.
