The weirdest combination I’ve ever met was a set of female twins. One was named after their mother. The other had a different first name. Must have been really odd when growing up.

Can confirm. I’ve lived in the Netherlands, France and Germany for basically all my life and I don’t recall ever actively saying thank you to a bus driver. I don’t even remember when last I exchanged any words with one thanks to modern fare systems.

On the contrary I say thank you to cashiers at the supermarket or staff at the bakery several times per week.
