re: People who end their emails with “Regards”

Better than the esquires that end it with “I remain very truly yours”.

Lawyers are really bad about sending their opposite number a nastygram and ending it with something like "my best personal wishes."

I use regards. I also frick with coworkers or close customers who use regards. I’ll change it to retards and call them saying “hey you realize your signature says retards right?” I’ll then send them a screenshot. They 100% of the time freak the frick out.

Well
Sometimes the recipient doesn't need to be thanked

It’s part of my email signature so yeah, I do it. I’m guessing you don’t get much email use over there at Los Pollos Hermanos?

You are a miserable bastard if this kind of shite rustles your jimmies

Nothing wrong with it. It's just a polite way of ending an email.

Now for those that write "many thanks", I find it weird. Just say thank you or thanks.

Cheers!

When i worked for a German based company we were encouraged to use Regards or With Kind Regards to sign off, especially when communicating with the Germans. I was told they dont really use pre-emptive thank yous and it comes off as odd.
