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.
“Please” is used more in verbal or formal communication in English. I wouldn’t typically use it when writing a comment here as online comment sections are considered informal written communication. But I would always say it if I was asking a food service worker for something.
