Thats “American style”, while keeping the fork in the non-dominant hand is “European style”. Allegedly, it dates back to when meals were served “service à la française”, which is when all courses are brought out at once, which is obviously the more common method of home cooking. Restaurants started doing “service à la Russe”, which is where courses are brought out one at a time.
With service russe, you have new sets of silverware with each course (or they are arranged in order), so if you are eating a course that doesn’t need a knife, you won’t be given one, and you’ll have your fork in your dominant hand. If you need a knife, that goes in your dominant hand, and you leave it there for the duration of the course.
With service française (or regular home cooking), you just have one set of silverware, and you only use the knife when you need it, so you might switch your fork to your dominant hand when you are done needing the knife.
For example, in America, no one eats a steak switching hands for every bite (cause that would be dumb and inefficient), and in Europe, you probably wouldn’t eat a meal that doesn’t need a knife with a knife in your dominant hand (cause that would also be dumb and inefficient).






A lot of these are really regional (alcohol drive-throughs, horse and buggy, air conditioning, gas appliances) . I think it’s been years since I saw anyone write a check for anything, though, with the exception of something to put into a birthday card. Horses also aren’t allowed on highways, but they are allowed on country roads that people drive pretty fast on.
Double hung vs single hung windows it not something I would have noticed, but I suspect you are right.
Doorknobs, I dont know why we seem to like them. I guess the only benefit vs handles is that you won’t snag your clothing on them when walking by. That doesn’t beat the convenience of being to open a door using your elbow while carrying something.
The water bottle thing is relatively recent thanks to all of the companies somehow becoming trendy.
