The city tourists photograph may depend on workers living outside the photograph.

The pleasant, well-run city in the photographs depends on people who cannot afford to live in it, commuting in early to clean, cook, and staff it, then travelling back out. The picture is possible because of people whose homes are deliberately outside the frame.

When you enjoy a place as a visitor, it is worth knowing what makes it work. Tip properly, be decent to the people serving you, and hold some awareness that the smoothness you are experiencing has a commute attached to it that you will never see.
