Minor nitpick, you have causality inverted. Esperanto is artificial and therefore regular.

While it’s nice for the employee to get some extra bucks, tipping only supports minimal pay for the job because “they’ll make up for it in tips”.

Also, you are in a forest. It is expected to see wild animals, it is unexpected to see humans. If you were in a seemingly empty office, would you rather see another person or a fucking bear?

I’ll answer the opposite way: in South America we have no crows, so it was by far the most fascinating animal I saw while in England.
