Hi Justin, the phrase "bedside manner" is very common, and was taken out of its original context for all kinds of uses because of medical drama TV shows. It basically means, "general human politeness for people you're caring for that are currently not in a confident position." This can apply to a medical professional that takes care of their patients, or a teacher watching over their students, or the person at Best Buy's Geek Squad explaining why your computer doesn't work. Rather than continuing to rile up the other user for no really good reason, perhaps you can accept that your lack of knowledge regarding common English idioms frustrated that other user, and forgive them for being mean to you. In the future, rather than make pedo jokes, maybe you'll give the phrase a look on Google to see if its been used before, because it likely has. Thank you for your time.

Thanks for taking time to explain things from your point of view.

I've seen the phrase used with medical professionals before.

Never with teachers or other situations though. The results and definition from the duckduckgo search (above) also only show it in use by medical professionals, not with others, and doesn't support your stated meaning.

Sounds like the phrase is used more widely in your part of the world. Good for you I guess. :)

I was leaning towards bad comedian, but now I'm leaning towards lead

Again with the unwarranted personal attacks. :(

Here's a tip: if you encounter this behavior in real life or online again you could simply not respond. It cancels the whole negative chain of communication.
