It's just a countryside thing, disappearing fast in today's metropolises? In the ~= 1000 people country village where I was born, when you saw a guy, know him/her or not, you said "good day". "Good morning", "Good afternoon", "Good evening" or even looking into his eyes, smiling and nodding. Today, my programmer colleagues can be split in three classes: 1) Guys who salute when they come in (to the office). 2) Guys who don't salute when they come into the office but salute me when I salute them. 3) Guys who don't salute when they come into the office and don't salute me when I salute them. I'm gonna get rid of the 3'rds. How's that sound with you? Nazi?
I think you are using the wrong terms here. You are using the term to be "salutation", which means to acknowledge someone. Yet you are typing "salute" in the tone of the physical gesture. And then you include the term "Nazi". So to be clear, you are just meaning a general greeting of "Hello" in words, or do you mean the Nazi salute with "Heil Hitler?" If the former, then no, it is not lost on folks in US companies in general, at least. Folks generally do say "Hi, how are you", or maybe a more formal "Good morning" or what-have-you. But sometimes a coworker is having a bad morning and doesn't say anything on their own to you to start. If the latter, well, no, the office spaces I've worked in do not Heil Hitler salute.
Yeah it would not go over well if an employee walked into my company and saluted with the Heil Hitler every morning. He or she would be fired.
Setting aside the usage problems that have been pointed out above, and the fact that you seem to be addressing your question to "Nazi"... ...it's a locality-based thing. I've just spent the summer in southern Colorado, where a house within rifle-shot of yours prompts mutters about "dang tourists buyin' the place up", and am moving back to the Tampa area, where your four nearest neighbors can easily reach into your pocket without moving from their easy chairs. In the first, everyone smiles and greets each other - and you're considered a churlish oaf (or at least asked "what's wrong?") if you don't do the same. In the second, doing so would cause people to freak out and call the police on you for stalker-like behavior. "When in Rome", home boy. First, figure out the context; then, adapt your behavior to it. Trying to force people to adapt to yours ain't going to win you any merit awards.
