The first time our German exchange student got a restaurant soda, he was upset they cheated with all the ice. We explained about free refills and he just couldn’t believe it. And free condiments. And free take home plastic drink cups. We sent him back with a bunch of plastic drink cups.
He also couldn’t get over the size of steaks in Texas or that bacon was more than just a flavoring ingredient.
I have heard Europeans have an abhorance of ice. Somehow cold drinks are seen as unhealthy or somehow decadent. It could also be that sky high electric rates make the operation of ice machines prohibitive.
