A couple of restaurants we frequent now serve soft drinks by the can. It's no big deal, the cost is about the same for the volume I usually drink at a restaurant.
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.
