In the service industry, everything is based on the principles of hypocrisy, as outlined in Carnegie's works. In the West, this has become one of the aspects of life and behavior, but here, no one has read Carnegie, and businesses simply copy the behavior patterns from the West, while our mentality remains the same.

Seriously, I don't rule out that the service industry had some influence here initially, but the point is not that; in general, the mentality is different, more "open." A smile to another person is your small personal success.
By the way, Sesame doesn't really share these observations in the West, hehe.
