It feels a bit like you didn't apply the lesson of the article - these "doormen" have often different functions (theft prevention or at least reduction, information provision, support for those that need help, some minor cleaning or caretaking roles, and the greeting/visibility/we-are-a-fancy-place vibe ;-)

In countries where labour is cheap it is common to have staff for less essential things as humans are just more flexible (but also less reliable) than machines.
