Hello,
First of all I don’t really get the actual meaning of “please”. I understand it as it used to make a polite request. However I have rarely seen any westerner saying “please” on either Lemmy, Mastodon or IRC. where I live using “please” (मेहरबानी) is used often.
People say it in person a lot. Another factor might be that some people view it coming across as either non genuine or passive aggressive in written form.
